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

What is the function of Pin 3 on the AP7383-36W5-7?

Pin 3 serves as the Enable (EN) input. A logic high voltage above 2.0V activates the regulator, while a voltage below 0.4V disables it.

Does the AP7383-36W5-7 require external compensation capacitors?

No external compensation is needed. The datasheet specifies that the device is compatible with standard low ESR ceramic capacitors, typically recommending 1µF input and output capacitors for stability.
