Product Overview

The LT3042EMSE#PBF is a 200mA High Performance RF Linear Regulator featuring 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, this can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB. The LT3042's wide output voltage range (0 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 4.7µF ceramic output capacitor. Built-in protection includes reverse battery protection, reverse current protection, internal current limit with fold back and thermal limit with hysteresis.
  • Ultralow RMS noise (0.8µVRMS, 10Hz to 100kHz)
  • Ultralow spot noise (2nV/√Hz at 10kHz)
  • Ultrahigh PSRR (79dB at 1MHz)
  • Single capacitor improves noise and PSRR
  • ±1% Initial accuracy 100µA SET pin current
  • Single resistor programs output voltage
  • High bandwidth (1MHz)
  • Programmable current limit
  • Low dropout voltage
  • Programmable power good
  • Fast start-up capability
