TYPICAL APPLICATION
DESCRIPTION
200mA 2-Terminal
Programmable Current Source
The LT
?/DIV>
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
output capacitors, offering high DC and AC impedance. This
feature allows operation in intrinsically safe applications.
The SET pin features 1% initial accuracy and low tem-
perature coef cient. Current regulation is better than
10ppm/V from 1.5V to 40V.
The LT3092 can operate in a 2-terminal current source
con guration in series with signal lines. It is ideal for driv-
ing sensors, remote supplies, and as a precision current
limiter for local supplies.
Internal protection circuitry includes reverse-battery and
reverse-current protection, current limiting and thermal
limiting. The LT3092 is offered in the 8-lead TSOT-23,
3-lead SOT-223 and 8-lead 3mm ?3mm DFN packages.
