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

Does the AP7350-18CF4-7 include an active discharge feature?

No, the standard AP7350 variant does not include an active output discharge feature. To achieve active discharge upon shutdown, the AP7350D version must be selected.

What is the recommended capacitor configuration for stability?

The datasheet recommends using a minimum 0.1µF ceramic input capacitor and a 0.1µF ceramic output capacitor placed as close to the device pins as possible to ensure stability and transient response.
