LM234Z-6/NOPB

Current Regulation/Management Overview

The LM234Z-6/NOPB is a three-terminal adjustable current source manufactured by Texas Instruments, housed in a TO-92 package. It operates within a supply voltage range of 1V to 40V and supports an output current up to 10mA. The device features an initial accuracy of ±6% and functions across a temperature range of -25°C to +100°C. Designed for through-hole mounting, it utilizes a single external resistor to set the current without additional components.

Current Regulation/Management Feature Summary

• Three-terminal adjustable current source architecture
• Wide dynamic voltage operation from 1V to 40V
• Single-resistor programmable current setting
• True floating current source capability

Current Regulation/Management Applications

• Precision bias networks
• Temperature sensing applications
• LED driver circuits
• Low-power reference sources

Current Regulation/Management Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm the ±6% accuracy grade. Ensure the TO-92 package variant matches the required thermal and mechanical constraints for the target application environment.

Current Regulation/Management Selection Notes

Select this component when a wide input voltage range and high current regulation stability are required. The ±6% accuracy specification suits general-purpose applications where tighter tolerances are not critical. Consider the operating temperature limits relative to the system's thermal profile.

Current Regulation/Management Part Context

This part belongs to the LM234 series of three-terminal adjustable current sources. It shares functional similarities with the LM134 and LM334 families but is distinguished by its specific accuracy grade and industrial temperature rating. The Z suffix indicates the TO-92 plastic package configuration.

Current Regulation/Management Replacement Considerations

LM234Z-3/NOPB offers higher precision at ±3% accuracy. LM334Z/NOPB provides a commercial temperature range alternative. Verify pinout compatibility and thermal performance before substituting.
