The IS31LT3172 and IS31LT3173 are adjustable linear current devices with excellent temperature stability.

A single resistor is all that is required to set the operating current from 10mA to 200mA.

Low-side current sink - Current preset to 10mA - Adjustable from 10mA to 200mA with external resistor selection.
Wide input voltage range from - 2.5V to 42V (IS31LT3173) - 5V to 42V (IS31LT3172) with a low dropout of typical 1V.
Up to 10kHz PWM input (IS31LT3173 only).
Protection features: - 0.26%/K negative temperature coefficient at high temp for thermal protection.
Up to 1.8W power dissipation in a small SOP-8EP package.
RoHS compliant (P.
