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

What is the minimum output capacitor value required for stability?

The device requires a ceramic output capacitor of at least 2.2µF with an ESR between 10mΩ and 300mΩ to ensure stability.

How does the enable pin function?

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