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

Does the NCV8170BMX250TCG support active output discharge?

Yes, the NCV8170 series includes an active discharge option that rapidly removes residual charge from the output capacitor when the enable pin is deactivated.

What type of capacitors are recommended for stability?

The device is stable with standard ceramic capacitors. X5R or X7R types with values of 1.0 µF or greater are recommended for both input and output decoupling due to their low capacitance variation over temperature.
