AP2127

300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR

Features Description

The AP2127 Series are positive voltage regulator ICs fabricated by

CMOS process.

The AP2127 Series have features of low dropout voltage, low noise, high output voltage accuracy, and low current consumption which make them ideal for use in various battery-powered devices.

AP2127 has 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.2V,

4.75V, 5.2V fixed voltage versions and 0.8V to 5.5V adjustable voltage versions.

AP2127 Series are available in SOT-23 (for fixed versions only),

SOT-23-3 (for fixed versions only), SOT-23-5, SOT-89 (for fixed versions only) and DFN-2x2-6 packages.

Application Notes

Input Capacitor

A 1µF ceramic capacitor is recommended to connect between V

IN

and GND pins to decouple input power supply glitch and noise. The amount of the capacitance may be increased without limit. This input capacitor must be located as close as possible to the device to assure input stability and less noise. For PCB layout, a wide copper trace is required for both V

IN

and GND.

Output Capacitor

The output capacitor is required to stabilize and help transient response for LDO. The AP2127 is stable with very small ceramic output capacitor with a low ESR 1µF or higher of X7R or X5R MLCC capacitor, which will be sufficient at full temperature ranges. Additional capacitance helps to reduce undershoot and overshoot during transient. Place output capacitor as close as possible to V

OUT

and GND pins, and keep the leads as short as possible.

Adjustable Operation

For adjustable version, the output voltage is calculated by:

V

OUT

=

V

REF

⎜⎜

1

+

R

1

R

2

⎟⎟

Where V

REF

= 0.8V (the internal reference voltage)

Rearranging the equation will give the following that is used for adjusting the output to a particular voltage:

R

=

R

⎜⎜

V

OUT

V

REF

⎟⎟

For AP2127, the resistor at the low side (R

2

) can be selected from 5kΩ to 200kΩ.

In order to improve the stability and to decrease the noise level of the adjustable version, a feed-forward capacitor is suggested to be placed between V

OUT

and ADJ pins (Figure 1). It’s recommended that this feed-forward capacitor value can be calculated as:

0.7kHz

The recommended value of the feed-forward capacitor for different resistor divider ratios is shown in the table below.

AP2127

Figure 1. Application Circuit with Feed-forward Capacitor

Current Limit Protection

When output current at V

OUT

pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to prevent over-current and to protect the regulator and load from damaged due to overheating.

Short Circuit Protection

When V

OUT

pin is shorted to GND, short circuit protection will be triggered and clamp the output current to approximately 50mA.

Auto discharge with Shutdown Version

For shutdown version, an auto discharge MOSFET with R

DS(ON)

of 60Ω typical is integrated between V

OUT

and GND pins, which can discharge the charge of the output capacitors quickly when turning off AP2127 with Shutdown pin.

Thermal Consideration

Internal thermal protection circuitry of AP2127 is used to protect device during overload conditions. For continuous operation, ensure not to exceed the operating junction temperature range of +125°C.

The power dissipation definition in the device is:

P

D

= (V

IN

- V

OUT

) x I

OUT

+ V

IN

x I

Q

The maximum power dissipation depends on the thermal resistance of IC package, PCB layout and the surrounding airflow. The maximum power dissipation can also be calculated as:

P

D(MAX)

= (T

J(MAX)

- T

A

) / θ

JA

The maximum power dissipation for SOT-23-5 package (least copper size) at T

A

= +25°C can be calculated as:

P

D(MAX)

= (125°C - 25°C) / (250°C/W) = 0.4W
