LT3668, 40V 400mA Step-Down Switching Regulator

.
The LT®3668 is a monolithic triple power supply composed of a 400mA buck switching regulator and two 200mA low dropout linear tracking regulators (LDO.

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 reve
