ANALOG DEVICES LT3042MPMSE#PBF LDO Voltage Regulator, Adjustable, 1.8-20Vin, 350mV Drop, 0 to 15V/0.2A Out, MSOP-10, -55 to 150 °C

LT3042MPMSE#PBF 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. This device supplies 200mA at a typical 350mV dropout voltage. The operating quiescent current is nominally 2mA and drops to <<1µA 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. Applications include 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.
