Description

The SC1564 is a high performance positive voltage regulator 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.
