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.

How does the AP7340 handle short circuits?

It features fold-back short circuit protection that clamps the output current to approximately 60mA when VOUT is shorted to GND.
