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 used for supply monitoring and sequencing. It goes into a high-impedance state when VOUT exceeds the threshold and is pulled low when VOUT drops below the threshold or the device is disabled.

How is the output voltage set for this specific model?

For the AP7347EQ-12FGECW-13A, the output voltage is fixed at 1.2V due to the internal integrated resistor network. No external resistors are needed for voltage setting.
