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:
V
OUT
= V
REF
(1 + (R
1
/R

)),
Where V
REF
= 1.24V.
Feedback resistor R2 should be no larger than 300kΩ.
