Semtech Corporation SC4205

The SC4205 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 1 Amp. The SC4205 provides exwww.DataSheet4U.com cellent regulation over variations in line, load and temperature. The SC4205 is available in the SOIC-8EDP package with internally preset outputs that are also adjustable using external resistors.

DESCRIPTION

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 SC4205 has an enable pin to further reduce power dissipation while shut down. SC4205

FEATURES

350mV dropout @ 1A Adjustable output from 1.2V to 4.8V 2.5V and 1.8V options (adjustable externally using resistors) Over current and over temperature protection Enable pin 10µA quiescent current in shutdown Low reverse leakage (output to input) Surface mount and through-hole packages Full industrial temperature range Available in SOIC-8EDP package
