LT3042EDD Integrated Circuit Chip Ultrahigh PSRR RF Linear Regulator 20V LDO Linear Regulator

Product Description Of LT3042EDD

LT3042EDD is a high performance low dropout linear regulator featuring LTC’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive RF applications. Designed as a precision current reference followed by a high performance voltage buffer, the LT3042EDD can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB.

LT3042EDD supplies 200mA at a typical 350mV dropout voltage. Operating quiescent current is nominally 2mA and drops to <<1μA in shutdown. It is stable with a minimum 4.7μF ceramic output capacitor. Built-in protection includes reverse battery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis.
