Description

The TLS102B0 is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG-

SCT595-5 package. The TLS102B0 is designed to supply off-board systems, for example sensors in powertrain

management systems under the severe conditions of automotive applications. Therefore, the TLS102B0 is

equipped with additional protection functions against reverse polarity as well as short circuit to GND and

battery. Up to a supply voltage of 40 V and up to an output current of 20 mA the output voltage follows the

reference voltage applied to the EN/ADJ input with very high accuracy. The required minimum reference voltage

at EN/ADJ is 2.0 V.
