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

How does the BYP pin affect output noise?

Connecting a 10nF capacitor between the BYP pin and the corresponding OUT pin reduces output voltage noise to 20µVRMS over a 10Hz to 100kHz bandwidth.

What is the minimum output capacitance required?

The device requires a minimum of 3.3µF output capacitance to prevent oscillations and ensure stability.
