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

What is the minimum output capacitance required for stability?

A ceramic output capacitor of at least 2.2µF is required. A 4.7µF capacitor is recommended for improved AC load response.

How does the short-circuit protection function?

When the output is shorted to ground, the device clamps the output current to approximately 400mA. Full current is restored once the output voltage exceeds 15% of its nominal value.
