HOW TO USE
<Setting of Output Voltage>
Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the values of
RFB11(RFB21) and RFB12(RFB22). The sum of RFB11(RFB21) and RFB12(RFB22) should normally be 1 M
or less.
VOUT = 0.9
×
( RFB11 + RFB12 ) / RFB12
[Example of Calculation]
When RFB11 = 200k
and RFB12 = 75k
, VOUT1 = 0.9
×
( 200K + 75k ) / 75k = 3.3V.
