Adjustable Regulator Application
Figure 10. Adjustable Voltage Application
MIC5239
The MIC5239YM can be adjusted from 1.24V to 20V by
using two external resistors (Figure 10). The resistors
set the output voltage based on the following equation:
V_OUT
=
V_REF
⎜⎛1
⎝
+
R1 _⎟⎞
R2 _⎠
Where VREF = 1.23V.
Feedback resistor R2 should be no larger than 300kΩ.
