MIC5233
Adjustable Regulator Application
The MIC5233BM5 can be adjusted from 1.24V to 20V by
using two external resistors (Figure 1). The resistors set the
output voltage based on the following equation:
VOUT
=
VREF

ï£ï£¬1+

ï£ï£¬
R1
R2



Where VREF = 1.24V.
Feedback resistor R2 should be no larger than 300kâ¦.
