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 device handle short circuits?

Short circuit protection triggers when VOUT is shorted to GND, clamping the output current to approximately 60mA to prevent damage.
