Product Brief
TLS208D1
Linear post regulator
The TLS208D1 is a monolithic integrated linear voltage post regulator. The IC regulates
an input voltage VI in the range of 2.7 V ≤ VI ≤ 18 V to an adjustable output voltage of
0.8 V to 5.25 V or to a fixed output voltage 3.3 V with a precision of ±2%. The TLS208D1 is
especially designed for applications with a permanent connection to preregulators like
DC/DC converters. The device is available in the small surface mounted DSO-8 (exposed
pad) package or an leadless TSON-10 with the capability for optical inspection. In addition to the enable functionality, the feature set includes a reset with an adjustable reset
threshold. The device is designed for the harsh environment of automotive applications.
Therefore it is protected against overload, short circuit and overtemperature conditions
by the implemented output current limitation and the overtemperature shutdown circuit.
