LT3092  
200mA 2-Terminal  
Programmable Current Source  
FeaTures  
DescripTion  
The LT®3092 is a programmable 2-terminal current  
source. It requires only two resistors to set an output  
current between 0.5mA and 200mA. A multitude of analog  
techniques lend themselves to actively programming the  
output current. The LT3092 is stable without input and  
outputcapacitors,offeringhighDCandACimpedance.This  
feature allows operation in intrinsically safe applications.

Available in 8-Lead SOT-23, 3-Lead SOT-223 and  
The LT3092 can operate in a 2-terminal current source  
configuration in series with signal lines. It is ideal for driv-  
ing sensors, remote supplies, and as a precision current  
limiter for local supplies.
