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

What is the purpose of the CE pin on the XC6701B612MR-G?

The CE (Chip Enable) pin controls the ON/OFF state of the regulator. Applying a high level activates the output, while a low level shuts it down, reducing power consumption to standby levels.

Can the XC6701B612MR-G operate with ceramic output capacitors?

Yes, the IC includes internal phase compensation, making it compatible with low ESR ceramic capacitors for the output stabilization capacitor without risk of oscillation.
