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

What is the logic level for the CE pin on the XC6204F series?

The CE pin operates with Active High logic, meaning the output is turned on when the CE pin is at a High level and turned off when at a Low level.

Does the XC6204F51AMR-G require external capacitors for stability?

Yes, it requires an output capacitor. The datasheet suggests using low ESR ceramic capacitors, such as 4.7μF for outputs between 0.9V and 1.2V, to ensure stability due to the built-in phase compensation.
