General Description

The IS32LT3177 and IS32LT3178 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 2.9V to 40V with a minimal voltage headroom of 1.0V (Typ.) at 150mA.

Key Features

  • 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 (IS32LT3178) - 5V to 40V (IS32LT3177) with a low dropout of typical 1.0V at 150mA.
  • Up to 1kHz PWM input (IS32LT3178 only).
  • Protection features: - 0.6%/K current roll off at high temp over 145°C for thermal protection - Output current limit - Thermal shutdown.
  • Up to 0.77W (SOT23-6)/2.32W (SOP-8-E.
