SC1566
Very Low Dropout
3.0 Amp Regulator With Enable
POWER MANAGEMENT
Description
The SC1566 is a high performance positive voltage
regulator designed for use in applications requiring very
low dropout voltage at up to 3 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 heat sink size reduction or elimination.
Additionally, the five pin versions of SC1566 have an
enable pin, to further reduce power dissipation while shut
down. The SC1566 provides excellent regulation over
variations in line, load and temperature.
The SC1566 is available as three terminal fixed output
voltage and five terminal fixed or adjustable output
voltage devices with enable. Two package options are
available: TO-263 and TO-220.
