Quality Control: Learn More
The STMicroelectronics L4931ABPT33-TR is a positive fixed output linear voltage regulator IC, designed for efficient power management in demanding applications. This component delivers a stable 3.3V output with a maximum current capability of 250mA, ideal for powering sensitive circuitry. It features a low quiescent current of 1mA and a maximum input voltage of 20V, with a dropout voltage of 0.8V at its full output current. Protection features include over-current and over-temperature shutdown, ensuring device reliability. The regulator offers excellent power supply rejection ratio (PSRR) ranging from 73dB to 55dB across the 120Hz to 10kHz frequency band. This device is supplied in a PPAK (TO-252-5, DPAK) surface-mount package, provided on tape and reel. Its robust performance makes it suitable for use in automotive, industrial, and consumer electronics sectors.
