LT3971 Datasheet (Linear Technology) - 2MHz Step-Down Regulator

LT3971, 2MHz Step-Down Regulator

The LT®3971 is an adjustable frequency monolithic buck switching regulator that accepts a wide input voltage range up to 38V.

Low quiescent current design consumes only 2.8µA of supply current while regulating with no load.

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