ADI LT3083EDF

Позитив14V3A

Overview

The LT3083EDF is a 3A low dropout linear regulator that can be paralleled to increase output current or spread heat on surface mounted boards. Architected as a precision current source and voltage follower, this new regulator finds use in many applications requiring high current, adjustability to zero, and no heat sink. The device also brings out the collector of the pass transistor to allow low dropout operation—down to 310mV—when used with multiple supplies.

Internal protection circuitry includes current limiting and thermal limiting. The LT3083EDF is offered in the 16-lead TSSOP (with an exposed pad for better thermal characteristics), 12-lead 4mm × 4mm DFN (also with an exposed pad), 5-lead TO-220, and 5-lead surface mount DD-PAK packages.
