Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the power-good pin function?

The PG pin is an open-drain output that goes high-impedance when VOUT exceeds the threshold and pulls low when VOUT drops below the threshold or the device is disabled.

What is the purpose of the active output discharge feature?

It ensures the output capacitor discharges rapidly when the device is disabled, guaranteeing a known state during system startup.
