EXTERNAL COMPONENTS
<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 RFB1 and RFB2. The sum of RFB1 and RFB2 should normally be 2 M
or less.
VOUT = RFB1 / RFB2 + 1
[ Example of Equation ]
VOUT = 3.0V
RFB1 = 200k
, RFB2 = 110k
, CFB = 68pF
VOUT = 220k / 110k + 1 =3.0V
