Description
The LD39130S is a high accuracy voltage regulator that provides 300 mA maximum current from an input voltage ranging from 1.4 V to 5.5 V, with a typical dropout voltage of 300 mV.
It is available in DFN6 1.2 x 1.3 mm package and in ultra-small CSP 4 bumps package, allowing the maximum space saving.
The device is stabilized with a ceramic capacitor on the output. The ultra-low drop voltage, low quiescent current and low noise features make it suitable for low power battery-operated applications. It integrates an internal logic circuitry, which allows the regulator to be in ultra-low consumption mode (green mode), when the output current required is very low. The normal working mode, with fast transient response, is restored when the load current increases.
The enable logic control function puts the LD39130S in shutdown mode allowing a total current consumption lower than 0.1 µA. The current foldback and thermal protection are provided.

Application information
Output voltage setting for ADJ version
In the adjustable version, the output voltage can be set from 0.8 V to the input voltage minus the voltage drop across the pass transistor (dropout voltage), by connecting a resistor divider between the ADJ pin and the output, allowing remote voltage sensing. The resistor divider can be determined using the following equation:
Equation 2
(1)
Even if the regulator is stable with no load, the maximum value for R
2
should not exceed 2 MΩ in order to ensure the best dynamic performance.
Soft-start function
The LD39130S has an internal soft-start circuit. By increasing the startup time up to 100 µs, without the need of any external soft-start capacitor, this feature keeps the regulator inrush current at startup under control.
Auto green mode function
The LD39130S integrates an internal logic circuitry, which allows the regulator to be in ultra-low consumption mode (green mode), when the output current required is very low.
When the auto green mode is enabled, the regulator automatically selects its operating mode, switching from a very low consumption operation at light loads, to a very fast transient response mode when the load current increases.
In the LD39130S, in DFN6 package, this function can be disabled by the user, by means of an external logic pin (GM). When the GM pin is set at high logic level, the device always operates in normal mode (fast transient response), while if the GM pin is set low, the auto green mode is enabled.
The LD39130SJ (CSP version) always operates in auto green mode.
Input and output capacitors
The LD39130S requires external capacitors to ensure the regulator control loop stability. These capacitors must be selected to meet the requirements of minimum capacitance and equivalent series resistance (see
Figure 32. Stability plan vs. (COUT, ESR)
). Locating the input/output capacitors as close as possible to the relative pins, is suggested.
Input capacitor
A capacitor with a minimum value of 1 µF is required at the input voltage of the LD39130S. This capacitor must be located as close as possible to the input pin of the device and returned to a clean analog ground. Any good quality ceramic capacitor can be used.
Output capacitor
The control loop of the LD39130S is designed to work with ceramic capacitors at the output.
The output capacitor must meet the requirements for the minimum amount of capacitance and E.S.R. (equivalent
series resistance) as shown in Figure 32. Stability plan vs. (COUT, ESR) .
The suggested value of 1 µF is a good choice to guarantee the stability of the regulator and to provide the optimum transient response. The output capacitor must maintain its ESR and capacitance in the stable region, over the full operating temperature range, to assure stability.
Output discharge function
The LD39130S integrates a MOSFET connected between V
OUT
and GND. This transistor is activated when the
EN pin goes to low logic level and has the function to quickly discharge the output capacitor when the device is disabled by the user.
