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

What is the minimum output capacitance required for stability?

The device is stable with a minimum output capacitance of 1µF ceramic capacitor.

How does the thermal shutdown function operate?

Thermal protection disables the output when the junction temperature reaches approximately +150°C and re-enables it when the temperature drops to approximately +130°C.
