Description
The TLS115B0 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 TLS115B0 is designed to supply off-board systems, for
example sensors in powertrain management systems under the severe conditions of automotive applications.
Therefore, the TLS115B0 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.
