Overview

Features n LT3668 40V 400mA Step-Down Switching Regulator with Dual Fault Protected Tracking LDOs Description The LT®3668 is a monolithic triple power supply composed of a 400mA buck switching regulator and two 200mA low dropout linear tracking regulators (LDOs).
This provides a complete and robust power solution for applications that require the power supply of a sensor to tightly track the power supply of a measurement ASIC.
Each tracking LDO supplies 200mA of output current with a typical dropout voltage of 340mV, and each LDO has an accurate resistor programmable current limit.
Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and rever...
