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

Does the AP7361EA-18Y5-13 support adjustable output voltage?

No, the '18' suffix indicates a fixed 1.8V output version. Adjustable versions require the blank suffix and utilize the ADJ pin.

What is the minimum output capacitance required for stability?

The datasheet recommends a ceramic output capacitor of at least 2.2µF for stable operation.
