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

What is the logic level for the CE pin on the XC6209B35AMR-G?

The 'B' designation indicates an Active High logic level. Additionally, this variant includes a built-in pull-down resistor, which prevents unstable operation if the CE pin is left open.

Does the XC6209B35AMR-G require an external capacitor for stability?

Yes, the datasheet recommends connecting an output capacitor (CL) of at least 1μF as close as possible to the VOUT and VSS pins to ensure stable phase compensation, particularly when using low ESR ceramic capacitors.
