Very Low Dropout, Low

Quiescent 500mA Regulator

POWER MANAGEMENT

Description

The SC1563 is a high performance positive voltage

regulator designed for use in applications requiring very

low dropout voltage at up to 500mA. Since it has supe-

rior dropout characteristics compared to regular LDOs, it

can be used to supply 2.5V on motherboards or 2.8V on

peripheral cards from the 3.3V supply with no heatsink.

Additionally, the SC1563 has a shutdown pin to further

reduce power dissipation while shut down. The SC1563

provides excellent regulation over variations in line, load

and temperature.

A wide range of fixed output voltage options are avail-

able. In addition, the output voltage of every device can

be adjusted between 1.2V and 4.8V using external resis-

tors. The SC1563 comes in the space saving 5-pin SOT-

23 package.
