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

What is the function of the PG pin?

The Power-Good (PG) pin is an open-drain output that indicates when the output voltage exceeds the threshold. It goes into a high-impedance state when VOUT is above the threshold and is pulled low when VOUT drops below it.

How is the EN pin operated?

The Enable (EN) pin turns the regulator on when driven high and puts it into shutdown mode when pulled low. It must not be left floating during operation.
