L4931ABD33-TR Description

Short technical summary and product information.

The STMicroelectronics L4931ABD33-TR is a linear voltage regulator IC designed for power management applications. It provides a fixed positive output voltage of 3.3V with a maximum output current of 250mA. The device features a low quiescent current of 1mA and a voltage dropout of 0.8V at 250mA.

 

Key electrical characteristics include an input voltage range up to 20V and protection features such as over current and over temperature shutdown. The PSRR is rated between 73dB and 55dB across a frequency range of 120Hz to 10kHz, indicating good noise rejection.

 

This component is housed in an 8-SOIC package suitable for surface mounting. The operating temperature range is -40°C to 125°C. Its fixed output and protective features make it suitable for various general-purpose power regulation tasks where a stable 3.3V supply is required.
