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

What is the function of the CE pin on the XC6210C series?

The CE pin controls the ON/OFF state. For the C-series, the device is active when the CE pin is Low and enters standby mode when the CE pin is High.

Does the XC6210C452DR-G require external feedback resistors?

No, the output voltage is fixed internally. External resistors are not needed for voltage setting, but input and output capacitors are required for stability.
