LM234Z-3/NOPB

Current Regulation/Management Overview

The LM234Z-3/NOPB is a three-terminal adjustable current source manufactured by Texas Instruments, housed in a TO-92-3 through-hole package. It operates within a supply voltage range of 1V to 40V and supports output currents up to 10mA. The device features an initial accuracy of ±3% and functions as a true floating current source without requiring separate power connections. It withstands reverse voltages up to 20V, allowing use in AC applications as both rectifier and current source. The operational temperature range spans from -25°C to +100°C.

Current Regulation/Management Procurement Notes

Verify the specific suffix designation against official datasheets to confirm intended performance characteristics. The '-3' variant indicates calibrated temperature sensing accuracy. Ensure procurement channels provide genuine Texas Instruments components with valid traceability documentation. Confirm RoHS compliance status matches project requirements before finalizing orders.

Current Regulation/Management Selection Notes

Select this component when a simple, single-resistor programmable current source is required. It is suitable for applications needing wide input voltage flexibility and high-side or low-side sensing capabilities. Consider the TO-92 package for through-hole designs. Evaluate thermal stability requirements against the specified operating temperature range.

Current Regulation/Management Part Context

This part belongs to the LM234 series of three-terminal adjustable current sources. It shares architectural similarities with the LM134 and LM334 but offers specific industrial-grade temperature ratings. The device provides a scalable solution for current regulation across microampere to milliampere ranges using minimal external components.
