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

What is the minimum required output capacitance for stability?

The device requires a minimum output capacitance of 10 µF with an equivalent series resistance (ESR) between 50 mΩ and 1.5 Ω.

How does the RESET pin function?

The RESET pin is an open-drain output that goes low when the output voltage drops below approximately 92% to 98% of its nominal value, indicating an undervoltage condition.
