of Functional Settings 1. Calculation equation to set the output voltage This IC controls the switching output so that the VOS pin voltage becomes 1.26V (typ).The equation to set the output voltage is as follows: R2 VO = 1+ × 1.26V(typ) R1 The VOS pin has the inrush current of 1µA (typ).Therefore, the error becomes larger when R1 and R2 resistance values are large.2. Start delay function The SS pin has the internally-connected 22µA (typ) constant-current supply.When the voltage of SS pin ex
