L4931ABD50-TR Description

Short technical summary and product information.

The STMicroelectronics L4931ABD50-TR is a fixed output linear voltage regulator designed for various applications requiring a stable 5V supply. It can deliver up to 250mA of output current with a low dropout voltage of 0.8V at 250mA. The device includes integrated protection features such as overcurrent and overtemperature shutdown, enhancing its reliability.

 

This regulator operates over a temperature range of -40°C to 125°C and is housed in an 8-SOIC surface mount package. Its PSRR characteristics range from 70dB to 55dB across the 120Hz to 10kHz frequency band, making it suitable for noise-sensitive applications. The positive output configuration and fixed voltage output simplify circuit design.

 

Key electrical specifications include a nominal output voltage of 5V and a maximum output current of 250mA. The device has a single regulator channel and is designed for surface mount installation, requiring appropriate PCB layout for thermal management.
