L4931CD50-TR Description

Short technical summary and product information.

The L4931CD50-TR is a low-dropout linear voltage regulator manufactured by STMicroelectronics. It delivers a fixed output voltage of 5V with a maximum output current of 250mA. The device features a typical dropout voltage of just 0.8V at 250mA load, making it suitable for battery-powered and low-voltage applications where headroom is limited.

 

The regulator includes built-in protection features such as over-current and over-temperature shutdown, enhancing system reliability. It operates over a wide temperature range of -40°C to 125°C, making it robust for industrial and automotive environments. The quiescent current is typically 1 mA, with a maximum supply current of 6 mA.

 

The L4931CD50-TR is offered in an industry-standard 8-SOIC (3.9mm width) surface-mount package and is available in Tape & Reel packaging for automated assembly. It is a low-cost, space-efficient solution for on-board power regulation.
