Description

Power Input pin.

Power-Good pin, open-drain output. When the V_OUTis below the

PG threshold the PG pin is driven low; when the V_OUTexceeds the

threshold, the PG pin goes into a high-impedance state. To use the

PG pin, use a 10kΩ to 1MΩ pull-up resistor to pull it up to a supply of

up to 5.5V, which can be higher than the input voltage.

Bias Input pin, provides input voltage for internal control circuitry.

This voltage should be higher than the V_IN.

VCC

Enable pin. This pin should be driven either high or low and must not

be floating. Driving this pin high enables the regulator, while pulling it

low puts the regulator into shutdown mode.

GND

Ground.

Soft-Start pin. Connect a capacitor between this pin and the ground

to set the soft-start ramp time of the output voltage. If no capacitor is

connected, the soft-start time is typically 100µS.

Feedback pin. Connect this pin to an external voltage divider to set

the output voltage.
