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

What is the minimum required capacitance for stability?

A 1.0µF capacitor is required between the output and ground for stability at standard loads. Lower values like 0.1µF are sufficient for currents below 1mA.

Can ceramic capacitors be used directly on the output?

Ceramic capacitors greater than 1000pF should not be connected directly due to low ESR. A series resistance of approximately 0.1Ω to 2Ω is recommended if using ceramics.
