Quality Control: Learn More
The STMicroelectronics L4947H is a fixed 5V positive linear voltage regulator with a 500mA output current capability. This device features a low quiescent current of 13mA and a maximum input voltage of 26V. The L4947H offers robust protection against over temperature, reverse polarity, and short circuit conditions. With a dropout voltage of 0.75V at 500mA and a power supply rejection ratio (PSRR) of 60dB at 120Hz, it is suitable for demanding applications. The regulator includes a reset function and is supplied in a 5-PENTAWATT package, designed for through-hole mounting. This component commonly finds application in automotive systems, industrial controls, and consumer electronics.
