Product Overview

The LT3042IDD#PBF is a high performance low-dropout Linear Regulator featuring LTCs ultra low 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 <<1µA in shutdown. Its wide output voltage range 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.
  • Fast start-up capability
  • Precision enable/UVLO
  • Parallelable for lower noise and higher current
  • 2nV/√Hz at 10kHz Ultralow spot noise
  • 100µA SET pin current - ±1% Initial accuracy
