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 1μA (typ).Therefore, the error becomes larger when R1 and R2 resistance values are large.ON Semiconductor and the ON logo are registered trademarks of Semiconductor Components Industries, LLC (SCILLC).SCILLC owns t
