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

What is the function of the NC pins on the SOT89 package?

The NC (Not Connected) pins are not connected internally but should be connected to GND on the PCB to maximize copper area for thermal dissipation.

Does the AP7383-44Y-13 include an enable pin?

No, the standard fixed-output version in the SOT89 package does not feature an enable pin; it operates continuously once powered.
