The LT3042IMSE#PBF by Analog Devices is a 200mA, ultralow noise, ultrahigh PSRR linear regulator. It features a wide input voltage range of 1.8V to 20V and an adjustable output voltage range from 0V to 15V. The device is designed for noise-sensitive RF applications, offering excellent power supply ripple rejection (PSRR) and low output noise.
Key electrical characteristics include a typical dropout voltage of 350mV at 200mA, a quiescent current of 2mA during operation, and less than 1µA in shutdown. The regulator also includes programmable current limit, fast start-up capability, and a programmable power good indicator. It is stable with a minimum 4.7µF ceramic output capacitor.
Built-in protection features include reverse battery protection, reverse current protection, internal current limit with foldback, and thermal limit with hysteresis. The LT3042IMSE#PBF is available in a thermally enhanced 10-MSOP-EP package and is suitable for surface mount applications.
This linear regulator is ideal for powering noise-sensitive components in RF applications such as PLLs, VCOs, mixers, and LNAs, as well as in very low noise instrumentation and high-speed data converters.
