|Abstract: PF1231-01 S1F78520 S1F78520 S1F78520 S1F78520 y r ina m Charge-pump Step Down Regulator with Power Saving Mode i rel P s DESCRIPTION The S1F78520 S1F78520 is a power IC which can generate two stabilized output voltages of 3.3 V (or 2.9 V or 2.5 V) and 2.5 V (or 2.0 V or 1.8 V) using the Li-ion battery. The 3.3 V range output is being generated through the LDO (series regulator). The 2.5 V range output is being generated through the charge pump type DC/DC converter consisting of built-in CMOS transistors. ...
