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 EN pin?

The EN pin enables or disables the regulator. Driving it high turns on the device, while pulling it low activates shutdown mode. It must not be left floating.
