AAP2967
Adjustable Operation
The adjustable version of the AAP2967 has an output
voltage range of 1.2V to 4.5V. The output voltage of the
AAP2967 adjustable regulator is programmed using an
external resistor divider as shown in Figure3. The output
voltage is calculated using:

Where:
Vref= 1.2V typ. (the internal reference voltage)
Utilize the following equation for adjusting the output to
a particular voltage:
