Quality Control: Learn More
STMicroelectronics L4947L is a linear voltage regulator IC featuring a fixed 5V output and a 500mA output current capability. This positive output regulator, housed in a 5-PENTAWATT package, offers a maximum input voltage of 26V and a typical dropout voltage of 0.75V at 500mA. Key protection features include over-temperature, reverse polarity, and short-circuit protection. The device also incorporates a reset function. With a quiescent current of 13mA and a power supply rejection ratio (PSRR) of 60dB at 120Hz, the L4947L is suitable for applications in automotive and industrial sectors. The operating temperature range is -40°C to 125°C.
