STMicroelectronics L4940V12 is a positive fixed 12V linear voltage regulator with a 1.5A output current capability. This TO-220-3 packaged device features an integrated regulator designed for reliable power delivery. Key specifications include a maximum input voltage of 17V, a dropout voltage of 0.9V at 1.5A, and a quiescent current of 8mA. Protection features include over-temperature, reverse polarity, and short-circuit protection. With a high power supply rejection ratio (PSRR) of 61dB at 120Hz, the L4940V12 is suitable for applications requiring stable voltage regulation in automotive, industrial, and consumer electronics. The device operates across a wide temperature range of -40°C to 150°C and is supplied in a TO-220 through-hole package.
