LD39130SJ33R Description

Short technical summary and product information.

The STMicroelectronics LD39130SJ33R is a linear voltage regulator designed for efficient power management. It offers a fixed output voltage of 3.3V and can supply up to 300mA of current. The device operates over a temperature range of -40°C to 125°C, making it suitable for various environmental conditions.

 

This regulator is housed in a compact 4-FlipChip (.69x.69) package, designed for surface mount applications. Key electrical characteristics include a low dropout voltage of 0.3V at 300mA and a quiescent current of 45 µA. Protection features such as over current, over temperature, and soft start are integrated to ensure reliable operation. The PSRR is rated at 70dB to 65dB across the 1kHz to 10kHz frequency range.

 

With its fixed output and robust protection, the LD39130SJ33R is well-suited for applications requiring stable voltage regulation in space-constrained designs. Its surface mount capability simplifies integration into printed circuit boards.
