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

How does the reverse current protection function?

The internal driver transistor prohibits reverse current flow when the VOUT voltage is higher than the VIN voltage, preventing battery current from flowing back into the regulator if a battery is connected to the output pin.

What is the purpose of the CE pin on the C/E type?

The CE pin enables the entire circuit to be placed in a stand-by state by inputting a low-level signal. The C/E type includes a pull-down resistor, ensuring the IC stops operation if the CE pin is left open.
