Adjustable Regulator Application

The MIC5225YM5 can be adjusted from 1.24V to 14V by

using two external resistors (Figure 1). The resistors set

the output voltage based on the following equation:

VOUT = VREF(1 + (R1/R2)),

Where VREF = 1.24V.

Feedback resistor R2 should be no larger than 300kΩ.
