3-Terminal Adjustable Current Source

The LM134 are 3-terminal adjustable current sources featuring 10,000:1 range in operating current, excellent current regulation and a wide dynamic voltage range of 1V to 40V. Current is established with one external resistor and no other parts are required. Initial current accuracy is ±3%. The LM134 is a true floating current sources with no separate power supply connections. In addition, reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.


  • Operates from 1V to 40V
  • 0.02%/V current regulation
  • Programmable from 1µA to 10mA
  • True 2-terminal operation
  • Available as fully specified temperature sensor
  • ±3% initial accuracy
