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

How does the CE pin function affect the output voltage during standby?

When a low-level signal is applied to the CE pin, the IC enters standby mode. For the H-type (included in this model), an internal auto-discharge switch activates, rapidly discharging the output capacitor and pulling the VOUT pin to the VSS level.

What is the maximum output current capability of this regulator?

The XC6222C261MR-G can deliver a maximum output current of 700mA under normal operating conditions, subject to thermal and current limit protections.
