GENERAL DESCRIPTION
The IS32LT3170 and IS32LT3171 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 (typical). Designed with a low dropout voltage; the device can drive LED strings close to the supply voltage without switch capacitors or inductors.

FEATURES
● 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 (IS32LT3171)
   - 5V to 42V (IS32LT3170)
   with a low dropout of typical 1V
● Up to 10kHz PWM input (IS32LT3171 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-free) package
● Automotive AEC-Q100 qualified

APPLICATIONS
● Automotive and avionic lighting
● Architectural LED lighting
● Channel letters for advertising, LED strips for
   decorative lighting
● Retail lighting in fridge, freezer case and
   vending machines
● Emergency lighting (e.g. steps lighting, exit way
   sign etc.)
