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

How is the Power-On Reset delay time configured?

The delay time is set by connecting an external capacitor between the SET pin and ground. The internal current source charges this capacitor until it reaches a threshold voltage.

What type of output capacitors are recommended for stability?

The device requires a 1µF ceramic output capacitor for each regulator. X7R or X5R dielectric types are recommended due to their temperature stability compared to Z5U or Y5V types.
