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

What is the function of the ON/OFF pin?

The ON/OFF pin controls the operational state. Setting it to a high level activates the regulator, while a low level stops internal circuits and reduces current consumption to the power-off level.

Is an output capacitor required for stability?

No, the device is designed to operate stably without an output capacitor. However, if used, a ceramic capacitor of 10 μF or less is recommended.
