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.

Programmable 2-Terminal Current Source

Maximum Output Current: 200mA

Wide Input Voltage Range: 1.2V to 40V

Input/Output Capacitors Not Required

Resistor Ratio Sets Output Current

Initial Set Pin Current Accuracy: 1%

Reverse-Voltage Protection

Reverse-Current Protection

The SET pin features 1% initial accuracy and low tem-

perature coefﬁcient. Current regulation is better than

10ppm/V from 1.5V to 40V.

<0.001%/V Line Regulation Typical

Current Limit and Thermal Shutdown Protection

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.

APPLICATIONS

2-Terminal Floating Current Source

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.
