DESCRIPTION  
FEATURES  
n
Internal Ballast Resistor Permits Direct  
The LT®3080-1 is a 1.1A low dropout linear regulator that  
incorporates an internal ballast resistor to allow direct  
paralleling of devices without the need for PC board trace  
resistors. The internal ballast resistor allows multiple  
devices to be paralleled directly on a surface mount  
board for higher output current and power dissipation  
while keeping board layout simple and easy. The device  
brings out the collector of the pass transistor to allow low  
dropout operation—down to 350mV—when used with  
multiple input supplies.

Wide Input Voltage Range: 1.2V to 36V  
Low Dropout Voltage: 350mV  
<0.001%/V Line Regulation  
The LT3080-1 is capable of supplying a wide output volt-  
age range. A reference current through a single resistor  
programs the output voltage to any level between zero  
and 36V. The LT3080-1 is stable with 2.2μF of ceramic  
capacitance on the output, not requiring additional ESR  
as is common with other regulators.  
Minimum Load Current: 0.5mA  
Stable with 2.2μF Minimum Ceramic Output Capacitor  
Current Limit with Foldback and Overtemperature

n
Available in 8-Lead MSOP and 3mm × 3mm DFN  
Internal protection includes current limiting and thermal  
limiting. The LT3080-1 regulator is offered in the 8-  
lead MSOP (with an Exposed Pad for better thermal  
characteristics) and 3mm × 3mm DFN packages.
