DESCRIPTION
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 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 the popular SO-8 surface mount package with two internally preset output voltage options, which are also adjustable using external resistors. Also available are 5-lead and 3-lead TO-220 2.5V options (fixed output only for the 3-lead option) and fixed output SOT-223 options.
