LT3080

Adjustable1.1A Single

Resistor Low Dropout

Regulator

FEATURES

DESCRIPTION

TheLT^®3080isa1.1Alowdropoutlinearregulatorthatcan

be paralleled to increase output current or spread heat in

surface mounted boards. Architected as a precision cur-

rent 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.

Outputs May be Paralleled for Higher Current and

Heat Spreading

Output Current: 1.1A

Single Resistor Programs Output Voltage

1% Initial Accuracy of SET Pin Current

Output Adjustable to 0V

Low Output Noise: 40μV

(10Hz to 100kHz)

RMS

Wide Input Voltage Range: 1.2V to 36V

Low Dropout Voltage: 350mV (Except SOT-223

Package)

A key feature of the LT3080 is the capability to supply a

wide output voltage range. By using a reference current

throughasingleresistor,theoutputvoltageisprogrammed

to any level between zero and 36V. The LT3080 is stable

with 2.2μF of capacitance on the output, and the IC uses

small ceramic capacitors that do not require additional

ESR as is common with other regulators.

<1mV Load Regulation

<0.001%/V Line Regulation

Minimum Load Current: 0.5mA

Stable with 2.2μF Minimum Ceramic Output Capacitor

Current Limit with Foldback and Overtemperature

Protected

Available in 8-Lead MSOP, 3mm × 3mm DFN,

5-Lead DD-Pak, TO-220 and 3-Lead SOT-223

Internal protection circuitry includes current limiting and

thermal limiting. The LT3080 regulator is offered in the

8-lead MSOP (with an exposed pad for better thermal

characteristics), a 3mm × 3mm DFN, 5-lead DD-Pak,

TO-220 and a simple-to-use 3-lead SOT-223 version.
