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

How does the power-good indicator function?

The power-good pin is an open-drain output that goes into a high-impedance state when the output voltage exceeds the threshold. If the output drops below the threshold or the device is disabled, the pin is pulled low.

What happens when the output is short-circuited?

Short-circuit protection triggers and clamps the output current to approximately 180mA, protecting the regulator from damage due to overheating.
