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 by an internal MOSFET if VOUT drops below the threshold or the device is disabled.

How is the output voltage set for this fixed version?

For the AP7347EQ-50FGECW-13A, the output voltage is internally fixed at 5.0V. No external resistor divider network is required, unlike the adjustable versions of the AP7347E series which use the FB pin for voltage setting.
