Texas Instruments LM334 3-Terminal Adjustable Current Source LM334SM

The LM334SM is a 3-terminal adjustable current source from Texas Instruments, capable of operating within a voltage range of 1V to 40V. It allows for programmable output currents from 1OºA to 10mA, with a current regulation of 0.02% per volt. The device features true 2-terminal operation, which simplifies circuit design by requiring only one external resistor to set the desired current. Initial accuracy is specified at ¬±3%, making it suitable for applications that require precise current sourcing. The LM334SM is designed for a temperature range of 0¬8C to +70¬8C and is available in various package types, including SOIC-8. It is applicable in bias networks, surge protection, LED driving, and temperature sensing, among other uses. The device also exhibits low reverse voltage characteristics, drawing minimal current under reverse conditions, which enhances its versatility in AC applications.
