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

How does the enable pin function?

The device is turned on when the EN pin is set to a logic high level and turned off when pulled low.

What happens during a short circuit condition?

Short circuit protection triggers and clamps the output current to approximately 400mA until the fault is removed.
