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 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-105FGECW-13A?

For this specific part number, the output voltage is internally fixed at 1.05V. The '105' code in the ordering information explicitly designates this fixed voltage level, distinguishing it from the adjustable versions which require external resistor dividers.
