Infineon TLS105B0MBHTSA1

The OPTIREG linear voltage regulator TLS105B0MB is a monolithic, integrated low-dropout voltage tracking regulator with high accuracy in small PG-SCT595-5 package. The TLS105B0MB is designed to supply off-board systems, for example sensors in powertrain management systems under the severe conditions of automotive applications. The TLS105B0MB provides protection functions against reverse polarity as well as against short circuit to GND and to battery. The output voltage follows the reference voltage applied to the EN/ADJ input with very high accuracy, up to a supply voltage of 40 V and up to an output current of 50 mA. The required minimum reference voltage at EN/ADJ is 2.0 V.
