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

What is the function of the FB/NC pin on the V-DFN3030-8 package?

For the fixed output version like AP7347EQ-30FGECW-13A, the FB/NC pin is a No Connect. It is not connected internally but should be connected to GND on the PCB to maximize copper area for thermal dissipation.

How does the Power-Good (PG) pin operate?

The PG pin is an open-drain output. It goes into a high-impedance state when VOUT exceeds the PG threshold and is pulled low by an internal MOSFET when VOUT drops below the threshold or the device is disabled.
