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

What is the function of the BYP pins?

The BYP pins allow connection of an external capacitor to ground to reduce output voltage noise by bypassing the internal reference.

How does the active shutdown feature work?

When the enable pin is driven low, the regulator enters a zero off-mode current state, and an internal N-channel MOSFET discharges the output capacitor and load.
