DESCRIPTION
The SC1563 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 500 milliamps. Since
it has superior 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.
The SC1563 is available as a five terminal fixed or
adjustable output voltage device with enable. The
device is available in a 5-pin SOT-23 package and an
8-pin MSOP package for higher power dissipation/
lower junction temperature.
