The SC564 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 SC564 has a shutdown pin to further reduce power dissipation while in shut down mode. The SC564 provides excellent regulation in line, load and temperature variations.
