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

Does the AP7361EA-Y5-13 support adjustable output voltages?

No, the '33' designation in the base model indicates a fixed 3.3V output. Adjustable versions require the ADJ pin configuration found in other suffixes.

What is the purpose of the EN pin on this regulator?

The EN (Enable) pin allows the user to turn the regulator on or off via a logic-high or logic-low signal, facilitating power management in the system.
