SOFT-S
Enable Input (Active High). Pull the EN pin below 0.8 V to disable the regulator and enter the standby
mode operation.
Ground
Inverting input of the error amplifier. The output voltage is sampled by means of a resistor divider and ap‐
plied to this pin for regulation.
Programmable soft-start. An internal current source charges the capacitor connected to this pin. The soft-
start period ends once the voltage of the soft-start capacitor reaches 0.8 V.
Gate drive for external N-Channel MOSFET. It is also the buffered output of the error amplifier.
Power supply voltage input. Operating voltage range is from 4.5 to 13.5 V. A decoupling capacitor to GND
should be used. A minimum of 0.1 mF is recommended.
