General Description

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 2.8V to 42V with a minimal voltage headroom of 0.264V.

Key Features

  • Low-side current sink - Current preset to 10mA - Adjustable from 10mA to 150mA with external resistor selection.
  • Wide input voltage range from - 2.8V to 42V (IS31LT3171) - 5V to 42V (IS31LT3170) with a low dropout of 0.5V.
  • Up to 10kHz PWM input (IS31LT3171 only).
  • Protection features: - 0.2%/K negative temperature coefficient forthermal protection - Open circuit and over voltage protection.
  • Up to 1W power dissipation in a small SOT23-6 package.
  • RoHS compliant (Pb-fr.
