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

How does the reference bypass pin affect noise performance?

Connecting an external capacitor to the reference bypass pin allows users to adjust the noise filter, enabling optimized low noise and high PSRR performance for sensitive applications.

What is the shutdown current consumption?

When both enable pins are driven low, the device enters shutdown mode, typically drawing less than 0.1µA of current.
