3.5 Adjusting the Output Voltage

The output voltage is set using the following equation where R2 is connected between the FB pin and GND, and R1 is connected between VOUT and FB.

Equation 1. GUID-5B0F9059-2788-4DBB-9822-E123B59BF26E-low.png

Adjusting the output voltage will affect the performance of the LM27342. In addition, output capacitors might not be rated for the new output voltage. Refer to the LM27342 data sheet for more information.
