MILPITAS, CA - February 23, 2015 - Linear Technology Corporation announces the LT3042, a leading-edge, ultralow noise, ultrahigh power supply ripple rejection (PSRR) low dropout voltage linear regulator. Its unique design features ultralow spot noise of only 2nV/√Hz at 10kHz and 0.8µVRMS integrated output noise across a wide 10Hz to 100kHz bandwidth. Low and high frequency PSRR performance are exceptional. Low frequency PSRR exceeds 90dB out to 10kHz and high frequency PSRR exceeds 75dB out to 3MHz, quieting noisy or high ripple input supplies. The LT3042 utilizes LTC’s proprietary LDO architecture-a precision current source reference followed by a high performance unity gain buffer, resulting in virtually constant bandwidth, noise, PSRR and load regulation performance independent of output voltage. In addition, this architecture permits paralleling of multiple LT3042s to further decrease noise, increase output current and spread heat on a printed circuit board (PCB).
