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

What is the function of the CE pin?

The CE pin acts as an ON/OFF control. When the voltage is high (1.1V to 28.0V), the regulator is active. When low (0V to 0.35V), it enters stand-by mode.

Does the XC6216B402MR-G support external voltage adjustment?

No, the B-type designation indicates a fixed output voltage. External adjustment is available only in the C-type variants.
