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

How does the auto-discharge feature affect the output voltage during shutdown?

When a low-level signal is applied to the CE pin, an internal N-channel transistor connects the VOUT pin to VSS, discharging the output capacitor charge and quickly returning the output voltage to the VSS level.

What type of output capacitor is recommended for this regulator?

The datasheet recommends using ceramic capacitors for phase compensation. For an output voltage of 1.4V, a minimum capacitance of 6.8μF is required for stable operation.
