IS31LT3173 - Lumissil

IS31LT3173 10-TO-200MA CONSTANT-CURRENT LED DRIVER

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. The devices can operate from an input voltage from 2.5V to 42V with a minimal voltage headroom of 1V (typical). Designed with a low dropout voltage; the device can.
