The STMicroelectronics L4945 is a positive fixed 5V linear voltage regulator IC with a 500mA output current capability. This TO-220-3 packaged component offers a maximum input voltage of 26V and features robust protection against over temperature, over voltage, reverse polarity, and short circuit conditions. With a quiescent current of 13mA and a maximum supply current of 180mA, it achieves a dropout voltage of 0.75V at its full 500mA output. The L4945 also provides a Power Supply Rejection Ratio (PSRR) of 60dB at 120Hz. This device is suitable for applications in automotive, industrial, and consumer electronics requiring stable voltage regulation. It is available in tube packaging for through-hole mounting.
