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

What is the purpose of the CE pull-down function?

The CE pull-down function keeps the IC in stand-by mode even if the CE pin is left open, preventing unintended operation.

How does the CL auto-discharge feature work?

When entering stand-by mode, an internal switch discharges the electric charge at the output capacitor, allowing the VOUT pin to quickly return to the VSS level.
