The XC9801 s e rie s a re s te p -up cha rge p um p ICs which

p rovid e s ta b le, highly e ffic ie nt, p os itive volta ge s with the only

Input Voltage Range: 1.8V ~ 5.5V

Output Voltage Range: 2.5V ~ 5.2V

Small Input Current: 80µA (no loa d )

Output Current: 80m A (3.6V → 5V s te p -up )

Oscillation Frequency: 300kHz

Stand-By Current (CE 'L'): 2.0µA (m a x)

Can be used as a Step-Up Doubler (sense = 0V)
