OPTIREG™ Linear Post Regulators

Infineon Technologies OPTIREG™ Linear Post Regulators are efficient power supply solutions for automotive Electronic Control Units (ECUs). The Infineon Technologies OPTIREG linear is designed for high efficiency, low noise, and small footprints. These regulators are ideal for use in conjunction with OPTIREG switchers. The OPTIREG linear portfolio includes various products for post-regulation, optimizing input voltage ranges. Operating after pre-switch mode converters, the devices enhance overall system efficiency in a pre-post supply architecture. This makes them well-suited for applications like infotainment, camera modules, radar, dashboards, and displays. Notably, Infineon's OPTIREG linear Post Regulator LDOs TLS205x, TLS203x, and TLS208x prioritize low noise performance, while the TLS202x variant is available in a compact SCT595 package for space efficiency.
