DESCRIPTION

AN30183A is a multi power supply LSI which has High-

Speed Response DC-DC Step Down Regulators (1-ch)

and LDO Regulators (4-ch).

By this DC-DC system, when load current charges

suddenly, it responds at high speed and minimizes the

changes of output voltage.

Since it is possible to use capacitors with small

capacitance and it is unnecessary to add external parts

for system phase compensation, this IC realizes

downsizing of set and reducing in the number of external

parts.

The output DC of each power supply is variable by I

control.
