LT3080 Adjustable1.1A Single Resistor Low Dropout
Regulator Description
The LT®3080 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 to be used in many applications requiring high current, adjustability to zero, and no heat sink. Also the device brings out the collector of the pass
transistor to allow low dropout operation —down to 350 millivolts— when used with multiple supplies.
A key feature of the LT3080 is the capability to supply a wide output voltage range. By using...
