LT3046 Overview
The LT3046 is a high-performance, low-dropout linear regulator featuring Analog Devices, Inc. ultra-low noise and ultra-high PSRR architecture for powering noisesensitive applications. Designed as a precision current reference followed by a high-performance voltage buffer, the LT3046 can be easily paralleled to further reduce noise, increase output current, and spread heat on the PCB.
