Texas Instruments Linear Voltage Regulator 35V Positive TO-220 3-Pin LM340T-15/NOPB

Texas Instruments LM340T-15/NOPB is a linear voltage regulator engineered for reliable fixed-voltage regulation in demanding electronic applications. As a three-terminal positive voltage regulator, it is designed to provide secure, regulated voltages to local circuits, mitigating distribution problems commonly seen with single-point regulation systems.

This regulator is housed in a TO-220 package, offering both durability and good thermal management capabilities. Its through-hole mounting makes integration straightforward for production or DIY electronics, and the positive polarity allows flexible use in a wide range of devices.

With a maximum input voltage of 35V and a minimum input voltage of 17.7V, the LM340T-15/NOPB supports robust regulation across typical voltage ranges required for industrial, laboratory, and commercial electronics. It delivers a maximum output current of up to 1A within the LM340 series, suitable for most board-level voltage needs.

Key features include internal current limiting, safe area compensation, and thermal shutdown circuitry, ensuring operational safety and reliability over prolonged periods. The TO-220 package dimensions (10.16mm length, 8.89mm height, 4.7mm width) make it compact for dense board layouts while maintaining effective heat dissipation.

Low quiescent current consumption at 8mA ensures efficient performance with reduced idle power usage, making it ideal for power management in sensitive and high-performance circuit designs. The 3-pin configuration provides ease of connection and assembly.

Industrially, this voltage regulator is suited for power management ICs, PCBs, and instrumentation across electronics manufacturing, laboratory equipment, and commercial automation systems requiring consistent voltage regulation.
