LT3975 Datasheet (Linear Technology) - 2MHz Step-Down Switching Regulator

LT3975, 2MHz Step-Down Switching Regulator

The LT®3975 is an adjustable frequency monolithic buck switching regulator that accepts a wide input voltage range up to 42V.

Low quiescent current design consumes only 2.7µA of supply current while regulating with no load.

Low ripple Burst Mode operation maintains high efficiency at low output curr
