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

What is the function of the PG pin on the AP7347E?

The Power-Good (PG) pin is an open-drain output that indicates when the output voltage exceeds the PG 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 the AP7347E-15FGECW-13A?

For this specific part number, the output voltage is fixed internally at 1.5V. Adjustable versions require external resistors connected to the FB/NC pin to set the desired output voltage between 1.0V and 5.0V.
