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

What is the minimum output capacitance required for stability?

The MIC5233 requires an output capacitor of 2.2µF or greater to maintain stability.

How does the enable pin function affect power consumption?

Driving the enable pin logic low disables the regulator into a zero off mode, consuming a typical ground current of 0.1µA.
