Infineon TLS115D0LD

The OPTIREG Linear TLS115D0 is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG-DSO-8 exposed pad and PG-TSON-10 packages. The TLS115D0 is designed to supply offboard systems, for example sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the TLS115D0 is equipped with protection functions against reverse polarity and against short circuit to GND and battery. Up to a supply voltage of 45 V and output currents up to 150 mA, the output voltage follows the reference voltage that is applied to the ADJ input with very high accuracy. The required minimum reference voltage at ADJ is 2.0 V.
