=1μF (Ceramic Capacitor: TAIYO YUDEN)

C1=0.47μF (Ceramic Capacitor: TAIYO YUDEN)

C2=4.7μF (Ceramic Capacitor: TAIYO YUDEN)

Note: The XC9801 series are step-up charge pump voltage doublers which provide regulated output voltage.

The application circuit of the doubler output (②) halts the regulated output function and operates as a normal voltage

doubler.

The output voltage is stable when connected as in (①) above, except when V
