DESCRIPTION
The SC1565 is a high performance positive voltage
regulator designed for use in applications requiring very
low dropout voltage at up to 1.5 Amps. 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 thus
allowing
the
elimination
Additionally, the 5-lead TO-220 and SO-8 versions
have an enable pin to further reduce power dissipation
while shut down. The SC1565 provides excellent
regulation over variations in line, load and temperature.
of
costly
heatsinks.
The SC1565 is available in the popular SO-8 surface
mount package with two internally preset output voltage
options, which are also adjustable using external
resistors. Also available are 5-lead and 3-lead TO-220
2.5V options (fixed output only for the 3-lead option)
and fixed output SOT-223 options.
