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

What is the function of the EN pin?

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

How does the AP7340D differ from the AP7340?

The AP7340D variant includes an internal N-channel auto-discharge resistor that discharges the output capacitor when the device is disabled.
