LT3042EMSE#TRPBF Description

LT3042EMSE#TRPBF developed by Linear Technology/Analog Devices is a type of high-performance low dropout linear regulator with ultralow noise and ultrahigh PSRR architecture that is designed to power noise-sensitive RF applications. It has the characteristics of the programmable current limit, fast start-up capability, and programmable power good. Wide output voltage range (0V to 15V) and unity-gain operation ensure virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage.
