Quality Control: Learn More
The STMicroelectronics L4931ABZ120 is a positive fixed 12V linear voltage regulator. This component delivers a stable 12V output with a maximum output current of 250mA. Designed for efficiency, it exhibits a quiescent current of 1.6mA and a maximum input current of 7mA. The device features robust protection mechanisms, including over-current and over-temperature shutdown. Its power supply rejection ratio (PSRR) ranges from 64dB at 120Hz to 55dB at 10kHz, ensuring clean output voltage. With a maximum input voltage capability of 20V and a dropout voltage of 0.8V at 250mA, this regulator is suitable for applications in automotive, industrial, and consumer electronics where reliable voltage regulation is critical. The L4931ABZ120 is supplied in a TO-92-3 package for through-hole mounting.
