The LM340T-15 from Texas Instruments is a monolithic 3-terminal positive voltage regulator designed for various applications requiring a stable 15V output. It can deliver up to 1.5A of output current, making it suitable for power supply designs. The device features internal current-limiting, thermal shutdown, and safe-area compensation, enhancing its robustness.
Key electrical specifications include an input voltage range of 7.5V to 35V, a typical dropout voltage of 2V at 1A, and a typical quiescent current of 6.5mA. The regulator offers a typical PSRR of 50dB at 100 KHz and an accuracy of 2.5%. It is available in fixed output voltage options of 5V, 12V, and 15V.
This component is housed in a TO-220-3 package, designed for through-hole mounting. The operating temperature range is from 0°C to 125°C. The LM340 series is known for its reliability and ease of use, often requiring minimal external components for stable operation.
Applications include on-card regulation for various electronic equipment, filtering post-regulators, and adjustable power supplies when used with external resistors. Its internal protection features make it a dependable choice for designs where component survival is critical.
