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

output capacitors, offering high DC and AC impedance. 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.

8-Lead 3mm × 3mm DFN Packages

AEC-Q100 Qualiﬁed for Automotive Applications

APPLICATIONS

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.
