Description

The LT3667 isa monolithic triple power supply composed of a400mA 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 below15mV in a typical application.

Each LDO supplies 200mA of output current with a typical dropout voltage of340mV, and each LDO has an accurate resistor programmable current limit.
