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.
