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

Does the AP7343Q-09FDZW-7 include an internal output discharge resistor?

No, the standard AP7343Q variant does not include an internal auto-discharge feature. The AP7343DQ variant includes this function.

What is the recommended capacitor configuration for stability?

The datasheet recommends using ceramic capacitors with low ESR. A minimum input capacitor of 0.47µF and an output capacitor are required for stability and transient response.
