LT3973 Datasheet (Linear) - Step-Down Regulator

LT3973, Step-Down Regulator

The LT®3973 is an adjustable frequency monolithic buck switching regulator that accepts a wide input voltage range up to 42V, and consumes only 2.5µA of quiescent current.

A high efficiency switch is included on the die along with the catch diode, boost diode, and the necessary oscillator, control a
