The IS31LT3177 and IS31LT3178 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. Designed with a low dropout voltage; the de.
• 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 (IS31LT3178) - 5V to 40V (IS31LT3177) with a low dropout of typical 1.0V at 150mA
• Up to 1kHz PWM input (IS31LT3178 only)
• ±5% current accuracy
• 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-EP) power dissipation in a small package
• RoHS & Halogen-Free Compliance
• TSCA Compliance
