The IS31LT3170 and IS31LT3171 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 150mA.

Low-side current sink - Current preset to 10mA - Adjustable from 10mA to 150mA with external resistor selection.
Wide input voltage range from - 2.5V to 42V (IS31LT3171) - 5V to 42V (IS31LT3170) with a low dropout of typical 1V.
Up to 10kHz PWM input (IS31LT3171 only).
Protection features: - 0.26%/K negative temperature coefficient at high temp for thermal protection.
Up to 1W power dissipation in a small SOT23-6 package.
RoHS compliant (Pb-.
