The Texas Instruments LM2940SX-5-0 is a positive fixed 5V linear voltage regulator with a 1A output current capability. This device features a low dropout voltage of 1V at 1A, making it suitable for applications where input-to-output voltage differential is critical. With a maximum input voltage of 26V and an output current of 1A, it offers robust performance. Protection features include over current, over temperature, reverse polarity, and short circuit protection. The device boasts a high power supply rejection ratio (PSRR) of 64dB at 120Hz. Supplied in a TO-263 (DDPAK-3) surface mount package, the LM2940SX-5-0 is commonly utilized in automotive, industrial, and consumer electronics where reliable voltage regulation is essential. It operates within a temperature range of -40°C to 125°C.
