LD39130SJ12R Description

Short technical summary and product information.

The STMicroelectronics LD39130SJ12R is a linear voltage regulator IC designed for positive fixed output applications. It provides a stable 1.2V output voltage with a maximum output current capability of 300mA.

 

Key electrical specifications include a maximum input voltage of 5.5V and a typical dropout voltage of 0.3V at 300mA. The quiescent current is rated at 45µA, making it suitable for power-sensitive applications. The device also features protection mechanisms such as over current, over temperature, and soft start.

 

This regulator operates across a wide temperature range of -40°C to 125°C. It is housed in a compact 4-FlipChip (.69x.69) package, specifically a 4-UFBGA, FCBGA, suitable for surface mount applications. The package is supplied on tape and reel.

 

Environmental compliance includes RoHS3 compliance and an MSL 1 rating. The device is designed for applications requiring a reliable and efficient linear voltage regulation solution.
