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

How should the ON/OFF pin be handled if it is not used?

For the 'B' type product indicated in the model number, connect the ON/OFF pin to the VIN pin when not in use to ensure normal operation.

What are the recommended external capacitor specifications?

An input capacitor (CIN) and an output capacitor (CL) of 1.0 µF or more are required. The equivalent series resistance (ESR) of the output capacitor must be 10 Ω or less.
