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

How does the XC6220C series handle the CE pin if it is left unconnected?

The XC6220C series includes a built-in CE pull-down resistor, which forces the IC into a standby (OFF) mode when the CE pin is left open.

What is the purpose of the CL auto-discharge feature in this model?

The CL auto-discharge feature allows the internal circuitry to quickly discharge the electric charge stored in the output capacitor when the IC is turned off via the CE pin.
