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

How does the XC6901DA01ER-G handle output discharge in standby mode?

When the CE pin is set to a low level, an internal auto-discharge switch activates, discharging the charge on the output capacitor to quickly return the -VOUT pin to the VSS level.

What protection features are integrated into this regulator?

The device includes over-current protection with a foldback characteristic and a thermal shutdown circuit that activates when the junction temperature reaches the limit.
