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

The application circuit of the doubler output (

) halts the regulated output function and operates as a normal

voltage doubler.

The output voltage is stable when connected as in (

) above, except when VIN < (VOUT / 2) and VIN

≥ VOUT.
