About

The ultimate solution for stable automotive applications

These range of LDOs ensure stability with the smallest 1 µF output capacitors bringing overall BOM cost savings in various automotive applications like BCM, HVAC, decentralized lighting modules, dashboards, and access control among others to supply loads such as microcontrollers and transceivers.

Lowest dropout voltage and safety watchdog features

Infineon OPTIREG™ linear high-performance LDOs TLS805x, TLS810x devices are optimized for lowest quiescent current down to 5 µA.

Infineon OPTIREG™ linear high-performance LDOs TLS820x2, TLS835x2, TLS850B0 devices are high-current products optimized for lowest quiescent current down to 20 µA.

Infineon OPTIREG™ linear high-performance LDOs TLS820x0, TLS850x0 offer the lowest dropout voltage and watchdog feature among others.

Operational in even the harshest environmental conditions

All high-performance LDOs are designed to be operational in a harsh automotive environment and implement automotive-specific feature sets. To further improve stability and robustness, products were designed and tested with LV124 requirements flow, which is unique and helps to improve quality in the field and minimize design effort and cost.
