Product Description
Texas Instruments LM340T-12/NOPB is a fixed positive voltage regulator designed to provide a stable 12V output at up to 1 ampere current. Packaged in a TO-220 3-pin form factor, it supports through-hole mounting and offers robust protection features including internal current limiting, safe area compensation, and thermal shutdown. The device operates reliably with a maximum input voltage of 35V and withstands operating temperatures up to 125°C, making it suitable for demanding industrial and electronic applications.
The LM340 series regulators are well regarded for providing local on-card regulation which can eliminate distribution problems associated with single point regulation. With a low quiescent current of 8mA, this regulator is energy efficient and ideal for power management circuits in industrial machines, laboratory equipment, manufacturing systems, and consumer electronics.
The device comes with 3 pins and a compact size measuring approximately 10.16mm in length, 8.89mm in height, and 4.7mm in width. Its positive polarity design ensures fixed voltage output without the need for external components unless output adjustment is desired.
These voltage regulators are common in applications requiring regulated power supplies with fixed voltage outputs, such as embedded systems, instrumentation, and industrial automation. Their durable packaging and internal protection enhance reliability in harsh environments.
