SC1565
Very Low Dropout
1.5 Amp Regulator With Enable
POWER MANAGEMENT
Revision: November 25, 2009
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 of costly heatsinks. Additionally,
the 5-lead TO-220/TO-263 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.
The SC1565 is available in SO-8, 3-lead SOT-223, 3 and
5 lead TO-220 and 3 and 5 lead TO-263 packages. Three
lead packages are available with 1.8V and 2.5V fixed
output options only. The SO-8, TO-220-5 and TO-263-5
are available with 1.8V and 2.5V internally preset
outputs that are also adjustable using external resistors.
