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

How does the CE pin behave when left open?

For Type H devices like this model, an internal pull-down resistor fixes the CE pin to a Low level, placing the device in stand-by mode if not actively driven High.

What is the purpose of the inrush current prevention circuit?

It limits the initial surge current flowing from VIN to VOUT during startup to approximately 95mA, protecting the input source and output capacitor.
