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

What is the function of the EN pin?

The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low activates shutdown mode.

How does the AP7341D differ from the standard AP7341?

The 'D' suffix indicates the presence of a built-in active discharge circuit that rapidly discharges the output capacitor when the device is disabled.
