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

What is the function of the EN pin?

The EN pin acts as an active-high enable input. Setting it to a logic high turns the regulator on, while pulling it low disables the output.

How does the device handle short circuits?

It features fold-back short circuit protection that clamps the output current to approximately 400mA when the output is shorted to ground.
