Description
The SC1564 is a high performance positive voltage reg-
ulator designed for use in applications requiring low
dropout voltages up to 600mA. 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 SC1564 has a shutdown pin to further
reduce power dissipation while in shut down mode. The
SC1564 provides excellent regulation in line, load and
temperature variations.
The output voltage of every device can be selected to
be 1.5V or adjusted between 1.2V and 4.55V. The SC1564
comes in a space-saving 3mm x 3mm x 1mm MLPD-8
package.
