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 puts the device into shutdown mode.

Does the AP7351D-30FS4-7B include output discharge?

Yes, the 'D' in the part number indicates that the device includes an active output discharge feature to rapidly discharge the output capacitor when disabled.
