AP7361C
Adjustable Operation
The AP7361C provides output voltage from 0.8V to 5.0V through external resistor divider as shown below.

Adjustable Output
Where VREF = 0.8V (the internal reference voltage)
Rearranging the equation will give the following that is used for adjusting the output to a particular voltage:

To maintain the stability of the internal reference voltage, R2 needs to be kept smaller than 80k.
