Overview
The PTN78000WAS is a high-efficiency, step-down Integrated Switching Regulator (ISR) produced by Texas Instruments. It represents the third generation in the evolution of the popular 78ST100 series of products. This regulator is designed to be smaller and lighter than its predecessors, offering either similar or improved electrical performance characteristics. The PTN78000WAS is packaged in a case-less, double-sided surface mount module, which enhances thermal characteristics and complies with TI's roadmap for RoHS and lead-free requirements.
