Add To BomL4940V12 General Description
The L4940V12 is a fixed voltage regulator designed by STMicroelectronics. It provides a stable 12V output voltage with a maximum load current of 1.5A. The device offers a dropout voltage of 1.3V at full load, making it suitable for applications where input voltage may vary close to the output voltage.The L4940V12 is housed in a TO-220 package, which allows for easy mounting on a PCB and efficient heat dissipation. It features internal current limiting and thermal shutdown protection to ensure the safety and reliability of the circuit.This voltage regulator operates within a wide input voltage range of 14V to 35V, making it ideal for use in various power supply applications. It has a high ripple rejection ratio of 80dB at 1kHz, ensuring a stable output voltage even in noisy environments.
