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

What is the function of the CE pin?

The CE (Chip Enable) pin allows the user to turn the output on or off. When the CE pin is at a high level (1.1V to 28.0V), the regulator operates normally. When at a low level (0V to 0.35V), the output turns off and the IC enters standby mode.

Does the XC6216B642ER-G support ceramic output capacitors?

Yes, the regulator is compatible with low ESR ceramic capacitors for output stabilization, which simplifies the design and reduces the overall component count compared to regulators requiring specific tantalum or aluminum capacitors.
