APL5156
Application Information (Cont.)
Adjustable Regulator Application
The output voltage of APL5156 can be adjusted from 3V
to 20V by using two external resistors. 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 larger than 100kΩ and
smaller than 1MΩ. The resistors should be placed as
close the device as possible to avoid noise.
