Additional preview pages of the IS31LT3178 datasheet.

The IS31LT3177 and IS31LT3178 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 - Adjustable from 10mA to 150mA (SOT236)/200mA (SOP-8-EP) with external resistor selection.
Wide input voltage range from - 2.9V to 40V (IS31LT3178) - 5V to 40V (IS31LT3177) with a low dropout of typical 1.0V at 150mA.
Up to 1kHz PWM input (IS31LT3178 only).
±5% current accuracy.
Protection features: - 0.6%/K current roll off at high temp over 145°C for thermal protection - Output current limit - Thermal shutdown.
Up to.
