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

What is the minimum recommended output capacitance for stability?

The device requires a minimum output capacitance of 2.2µF ceramic capacitor to ensure stability and improve transient response.

How does the enable pin function?

The regulator turns on when the EN pin is set to a logic high level and turns off when pulled low. If unused, the EN pin should be tied to the IN pin.
