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

What is the function of the CE pin on the XC6503D series?

The CE pin allows turning off the entire circuit with a low-level input signal. The D-type includes a pull-down resistor to prevent unstable operation if the pin is left open.

Does the XC6503D20AMR-G require an output capacitor?

No, the device is designed to be stable without a load capacitor due to internal phase compensation, though an input capacitor is recommended.
