IS31LT3170 Datasheet (Lumissil) - 10-TO-150MA CONSTANT-CURRENT LED DRIVER

IS31LT3170, 10-TO-150MA CONSTANT-CURRENT LED DRIVER

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.

The devices can operate from an input voltage from 2.5V to 42V with a minimal voltage headroom of 1V (t
