The LT3042 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 LT3042 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB.The device supplies 200mA at a typical 350mV dropout voltage. Operating quiescent current is nominally 2mA and drops to <<1?A in shutdown. The LT3042?s wide output voltage range (0V to 15V) while maintaining unity-gain operation provides virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage. Additionally, the regulator features programmable current limit, fast start-up capability and programmable power good to indicate output voltage regulation.The LT3042 is stable with a minimum 4.7?F ceramic output capacitor. Built-in protection includes reverse battery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis. The LT3042 is available in thermally enhanced 10-Lead MSOP and 3mm ? 3mm DFN packages.Applications RF Power Supplies: PLLs, VCOs, Mixers, LNAs Very Low Noise Instrumentation High Speed/High Precision Data Converters Medical Applications: Imaging, Diagnostics Precision Power Supplies Post-Regulator for Switching Supplies
