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

What is the purpose of the PG pin on the AP7583AQ?

The PG pin serves as an open-drain output indicating when the regulated output voltage has reached its valid threshold, facilitating supply monitoring and sequencing.

How does the AP7583AQ handle overtemperature conditions?

Thermal shutdown protection disables the output when the junction temperature reaches approximately +175°C, re-enabling the circuit once the temperature drops to approximately +155°C.
