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

What is the minimum capacitance required for stability?

The device requires at least 1µF on both the input and output pins using MLCC capacitors to ensure stability.

How does the enable pin function?

The EN pin is active high; setting it to a logic high level turns the regulator on, while pulling it low disables the output.
