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

How is the Power-Good (PG) pin configured?

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

What is the function of the exposed pad on the V-DFN3030-8/SWP package?

The exposed pad is recommended to be connected to GND or left open in PCB layout to maximize copper area for better thermal dissipation, but it should not be used as the sole GND electrode.
