Description of Functional Settings
Calculation equation to set the output voltage
This IC controls the switching output so that the VOS pin voltage becomes 1.23V (typ).
The equation to set the output voltage is as follows:
VO = 1+
R2
R1
× 1.23V(typ)
The VOS pin has the inrush current of 1 μ A (typ). Therefore, the error becomes larger when R1 and R2 resistance
values are large.
