STMicroelectronics L4931ABDT33 is a fixed, positive linear voltage regulator designed for efficient power management. This component delivers a stable 3.3V output at up to 250mA, with a typical quiescent current of 1 mA and a maximum supply current of 6 mA. Featuring over-current and over-temperature protection, it operates reliably within a -40°C to 125°C temperature range. The device has a maximum input voltage of 20V and a dropout voltage of 0.8V at its full 250mA output. With a Power Supply Rejection Ratio (PSRR) ranging from 73dB to 55dB across the 120Hz to 10kHz spectrum, it effectively filters noise. The L4931ABDT33 is supplied in a DPAK (TO-252-3, DPAK (2 Leads + Tab), SC-63) surface-mount package, suitable for applications in automotive, industrial, and consumer electronics.
