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

Does the AP7361C-33E-13 support adjustable output voltages?

No, the '33' designation indicates a fixed 3.3V output. Adjustable versions are available with the 'ADJ' designation.

What is the function of the EN pin on this device?

The EN pin is an active-high enable input. Setting it to a logic high level turns the regulator on, while pulling it low shuts down the output.
