The Infineon OPTIREG linear voltage regulator is a monolithic, integrated low-dropout voltage tracking regulator with high accuracy in a small PG-TSON-10 package. The OPTIREG linear voltage regulator is designed to supply off-board systems, for example sensors in powertrain management systems under the severe conditions of automotive applications. The OPTIREG linear voltage regulator provides protection functions against reverse polarity as well as against short circuit to GND and to battery. The output voltage follows the reference voltage that is applied to the ADJ input with very high accuracy up to a supply voltage of 45 V and up to an output current of 150 mA. The required minimum reference voltage at ADJ is 2.0 V.
