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

What is the recommended output capacitor value for stability?

The PAM3110 is stable with a ceramic output capacitor of 4.7µF or higher.

How does the device handle over-temperature conditions?

The regulator features an over-temperature shutdown function that activates at 160°C and resumes operation once the device cools down approximately 30°C below the trip point.
