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

What is the function of the PG pin?

The Power-Good (PG) pin serves as an open-drain output that indicates when the output voltage has reached its regulated level. It goes into a high-impedance state when VOUT exceeds the threshold and pulls low if VOUT drops below the threshold or the device is disabled.

How does the device handle short circuits?

The AP7347E incorporates fold-back short-circuit protection. When the output is shorted to ground, the current limit circuit triggers and clamps the output current to approximately 180mA, protecting the regulator from damage due to overheating.
