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 power-good threshold. It goes into a high-impedance state when VOUT is above the threshold and is pulled low when VOUT drops below the threshold or the device is disabled.

How does the device handle short-circuit conditions?

When the output is short-circuited to ground, the internal protection circuitry clamps the output current to approximately 180mA to prevent damage from overheating.
