XC6220 Series
ETR0341-010a
1A LDO Voltage Regulator with “GreenOperation”
GreenOperation-Compatible
GENERAL DESCRIPTION
The XC6220 series is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with
GreenOperation function. The series consists of a voltage reference, an error amplifier, a current limiter, an inrush current
prevention circuit and a phase compensation circuit plus a driver transistor.
With a 0.2 on-resistance driver transistor integrated, the ultra low dropout voltage performance with output currents up to 1A
greatly extends battery life as does the GreenOperation function which can switch between high speed and power save modes
automatically. A low ESR ceramic capacitor can be used for the output stabilization capacitor (CL).
Output voltage is selectable in 0.05V increments within the range of 0.8V~5.0V, using laser trimming technologies.
An over current protection circuit and a thermal shutdown circuit are built in. The over current protection circuit will operate
when the output current reaches its limit current. The thermal shutdown circuit will operate when the junction temperature
reaches its limit temperature. The inrush prevention circuit works by controlling the inrush current which charges to CL when
the IC starts up. In this way, voltage fluctuations in power supply caused by inrush current during system start up can be
minimized.
The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power
consumption.

PIN CONFIGURATION
* For the USP-6C, the No.5 and 6 VIN pins should be connected. The No.1
and 2 pins VOUT pins should be connected. The dissipation pad should be
solder-plated in reference mount pattern and metal masking so as to
enhance mounting strength and heat release.
If the pad needs to be
connected to other pins, it should be connected to the VSS (No. 4) pin.
*For the SOP-8FD, two power input pins (No.7 and No.8) output pins (No.1
and 2) should be connected. The dissipation pad should be solder-plated
in electrically open or connecting to the VSS (No.4) pin.

* 1: VOUT (E) = Effective output voltage
(The output voltage when an amply stabilized "VOUT (T) 1.0V" is provided at the VIN pin while maintaining a certain IOUT value.)
* 2: VOUT (T) = Nominal output voltage. (Shown in the voltage chart E-0)
* 3: Vdif = {VIN1-VOUT1}
VIN1 is the input voltage when VOUT1 appears at the VOUT pin while input voltage is gradually decreased.
VOUT1 is the voltage equal to 98% of the HS mode output voltage when an amply stabilized VOUT (T) +1.0V are supplied to the VIN pin.
* 4: For the XC6220B/D series only. The XC6220A/C series (semi-custom) discharges by only R1 and R2 resistors as shown in the block diagrams.

OPERATIONAL EXPLANATION
The voltage divided by resistors R1 & R2 is compared
with the internal reference voltage by the error amplifier.
The P-channel MOSFET which is connected to the VOUT
pin is then driven by the subsequent control signal. The
output voltage at the VOUT pin is controlled & stabilized
by a system of negative feedback. The current limit
circuit and short protect circuit operate in relation to the
level of output current. The GO function monitors the
output current and switches the IC between two
operating modes according to the level of output
current. Further, the IC's internal circuitry can be
shutdown via the CE pin's signal.
<GreenOperation>
The XC6220 series always operates in a green operation (GO) mode.
The GO mode enables the IC to switch automatically between the high
speed (HS) mode or the power save (PS) mode according to the level of
output current. The switching point of the HS mode and the PS mode is
fixed inside the IC. When the output current becomes IGOR=1.0mA (MIN.)
or below, the mode changes automatically to the PS mode after a delay
time of hundreds of microseconds. Supply current in light load is greatly
reduced. Also when the output current becomes IGO 10mA (MAX.) or
more, the mode changes automatically to the HS mode and the IC
returns to high speed operation.
<Low ESR capacitor>
The XC6220 series has a built-in phase compensation circuit which means that a stable output voltage is achieved even if
the IC is used with low ESR capacitors. In order to ensure stable phase compensation it is recommended that a CL capacitor
is connected as close as possible to the VOUT pin and VSS pin. For a stable power supply, please connect an input capacitor
(CIN) between the VIN pin and the VSS pin.
Values required for the phase compensation are shown in the chart below. If a loss of the capacitance happens, the stable
phase compensation may not be obtained. Please ensure to use a capacitor which does not depend on bias or temperature
too much.

<Current Limiter, Short-Circuit Protection>
The XC6220 series includes a fold-back circuit, which aids the operation of the current limiter and circuit protection. When
the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this drop
in output voltage, output current also decreases. When the output pin is shorted, a current of about 180mA flows.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6220 series. With the XC6220A/C
series, output at the VOUT pin will be pulled down to the VSS level However, with XC6220B/D series, the CL auto-discharge
N-channel transistor switch is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin. Therefore,
the time until the VOUT pin reaches the VSS level is shortened. The output voltage of the XC6220A/B series becomes
unstable, when the CE pin is open. If this IC is used with the correct output voltage for the CE pin, the logic is fixed and the
IC will operate normally. On the other hand, with the XC6220C/D series, the IC operation is stopped when the CE pin is
open. However, the CE pin input current may increase as a result of through current in the pull-down resistor (RCE) when the
IC is under operation.

XC6220 Series
OPERATIONAL EXPLANATION (Continued)
<CL Discharge Function>
The XC6220B/D series can quickly discharge the electric charge at the output capacitor (CL) via the N-channel transistor
located between the VOUT pin and the VSS pin, when a low signal is inputted to the CE pin, which enables the whole IC circuit
put into an OFF state (cf. BLOCK DIAGRAM).
(VOUT pin voltage) ÷ (N-channel transistor through current) = CL discharge resistance (RDCHG)
The CL auto-discharge resistance value is fixed to 460 (VIN=6.0V, VOUT=5.0V at TYP.). The discharge time of the output
capacitor (CL) is set by the CL auto-discharge resistance (RDCHG) and the output capacitor (CL). By setting a time constant of
the CL auto-discharge resistance value [RDCHG] and an output capacitor value (CL) as
( =C x RDCHG), the output voltage
after discharge via the N-channel transistor is calculated by the following formulas.
V = VOUT(E) x e –t/ ,
or
OUT(E)
where
V : Output voltage after discharge
VOUT(E) : Output voltage
t: Discharge time
: CL auto-discharge resistance RDCHG×Output capacitor (CL) value C)
<Inrush Current Prevention>
The XC6220 series includes an inrush current Prevention circuit.
The inrush current protection circuit suppresses inrush current charged to CL when the IC starts up to 700 mA (MAX.) for
approximately 1ms.
* Please note that the device can not provide the output current beyond 700 mA for a period of approximately 1ms after the
CE pin goes high.
NOTES ON USE
1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output
current. Please strengthen VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
4. As for the XC6220A/C series (semi-custom), the output voltage may float with a leakage current of the driver transistor
between VIN and VOUT and R1+R2 resistance while stand-by (operation stop). Please take consideration of this and check it
before use.
5. Torex places an importance on improving our products and their reliability. We request that users incorporate fail-safe
designs and post-aging protection treatment when using Torex products in their systems.
