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 is the output voltage determined for this part number?

For the AP7347E-30FGECW-13A, the output voltage is fixed internally at 3.0V. This is indicated by the '30' code in the part number sequence. Adjustable versions require external resistors connected to the FB/NC pin.
