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

What is the function of the EN pin on the AP7353-36CV4-7?

The EN pin controls the operation of the regulator. Driving it high enables the output, while pulling it low activates the shutdown mode.

Does the AP7353-36CV4-7 include an auto-discharge feature?

No, the standard AP7353 does not include an auto-discharge feature. The AP7353D variant includes this functionality.
