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

What is the function of the EN pin on the AP7362A-33SP-13?

The EN pin is an active-high enable input. Setting it high turns the device on, while pulling it low turns the part off, allowing for logic-controlled power management.

How does the AP7362 handle over-temperature conditions?

The device features thermal shutdown protection that disables the output when the junction temperature rises to approximately +170°C. The output re-enables when the temperature drops to approximately +160°C.
