LM334M Description

Short technical summary and product information.

The LM334M is a 3-terminal adjustable current source designed by Texas Instruments. It operates from a 1V to 40V input voltage range and provides a programmable output current from 1µA to 10mA. The device features an initial accuracy of ±3% and is ideal for biasing, sensor excitation, and current limiting applications.

 

This current source is housed in a standard 8-SOIC surface-mount package (0.154", 3.90mm width) with an MSL of 1 (unlimited). The operating temperature range is -40°C to 85°C, making it suitable for a wide range of industrial and commercial environments. The LM334M does not require external resistors for basic operation and is fully adjustable via a single external resistor.

 

With a maximum current regulation of 10mA and a simple 3-terminal design, the LM334M offers a compact and reliable solution for precision current sourcing in power management circuits. Its wide input voltage range and low dropout capability allow use in both low-voltage and high-voltage systems.
