The STMicroelectronics L4931ABV33 is a positive fixed voltage linear regulator IC designed for general-purpose power supply applications. This component delivers a stable 3.3V output with a maximum current capability of 250mA. It features over-current and over-temperature protection for robust operation. The device offers a typical quiescent current of 1mA and a supply current of 6mA (max). With a maximum input voltage of 20V and a dropout voltage of 0.8V at 250mA, it is suitable for applications requiring efficient voltage regulation. The L4931ABV33 is housed in a TO-220-3 through-hole package, facilitating easy integration into circuit designs. This regulator finds application in automotive, industrial, and consumer electronics sectors. Its Power Supply Rejection Ratio (PSRR) ranges from 73dB at 120Hz to 55dB at 10kHz, ensuring effective filtering of input voltage ripple.
