LT3667 datasheet

 

Description :

The LT3667 is a monolithic triple power supply composed of a 400mA buck switching regulator and two 200mA low dropout linear regulators (LDOs).

The buck regulator includes a high efficiency switch, a boost diode, and the necessary oscillator, control and logic circuitry. Current mode topology is used for fast transient response and good loop stability. Low ripple Burst Mode operation maintains high efficiency at low output currents while keeping output ripple below 15mV in a typical application.

Each LDO supplies 200mA of output current with a typical dropout voltage of 340mV, and each LDO has an accurate resistor programmable current limit.

Applications

1. Automotive Battery Regulation
2. Power for Portable Instrumentation
3. Industrial Supplies
4. Fault-Protected Sensor Supply
