Product Description

Texas Instruments LM340AT-5.0/NOPB is a robust positive voltage regulator designed for fixed voltage regulation requirements in industrial, commercial, and electronic applications. Housed in a TO-220 package, this device supports a maximum input voltage of 35 V and a minimum input voltage of 7.5 V, offering flexibility for various power supply designs.

With a 3-pin through-hole configuration, installation and integration into PCB designs is straightforward. The regulator is engineered with internal safety features including current limiting, safe area compensation, and thermal shutdown, ensuring dependable protection against overload and high-temperature conditions.

The LM340 series delivers up to 1 A output current (for select variants), supporting stable power delivery for moderate to high-load circuits. Typical quiescent current is 6 mA, which enhances efficiency and reduces unwanted drain during operation. The regulator achieves positive voltage regulation, catering to applications such as microcontroller power management, sensor arrays, and on-card regulation in distributed systems.

Dimensionally, the regulator features a compact footprint of 10.16 mm length, 4.7 mm width, and 8.89 mm height, suiting PCB layouts with limited space. The device is capable of operating at temperatures up to 125°C, making it ideal for demanding environmental conditions commonly encountered in laboratory, manufacturing, and industrial use cases.

Texas Instruments LM340AT-5.0/NOPB is widely used in areas including industrial controls, laboratory instrumentation, automation systems, and power management modules. Its combination of robust protections, easy mounting, and reliable voltage regulation make it a preferred choice for electronic component designers and manufacturers.
