LT3080ET#PBF Description
The LT3080ET#PBF is a 1.1A low dropout linear regulator that can be paralleled to increase output current or spread heat in surface-mounted boards. Architected as a precision current source and voltage follower allows this new regulator is to be used in many applications requiring high current, adjustability to zero, and no heat sink. Also, the LT3080ET#PBF brings out the collector of the pass transistor to allow low dropout operation —down to 350 millivolts—when used with multiple supplies.
