LM334M Description

Short technical summary and product information.

The STMicroelectronics LM334M is a versatile 3-terminal adjustable current source designed for a wide range of applications. It operates from a broad input voltage range of 0.8V to 40V, providing excellent current regulation with a typical value of 0.02%/V. The output current is programmable from 1µA to 10mA, making it suitable for various low-power designs.

 

This current source features true 2-terminal operation and can be configured with a single external resistor. Its initial accuracy is typically within ±3%. The LM334M is available in both TO-92 and SOIC packages, supporting through-hole mounting. It can also function as a temperature sensor due to its proportional-to-absolute-temperature sense voltage.

 

Applications include bias networks, surge protection, and low-power reference circuits. The device's ability to act as a rectifier and current source in AC applications, drawing only microamperes of current when reverse-biased up to 20V, adds to its utility.
