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

What is the purpose of the PG pin?

The Power-Good (PG) pin is an open-drain output that indicates when the output voltage exceeds the threshold. It can be used for supply monitoring or sequencing other supplies.

How does the device handle short circuits?

The regulator includes a fold-back short-circuit current limit that clamps the output current to approximately 180mA when the output is shorted to ground, protecting the device from damage.
