Description

The TLS208D1 is a monolithic integrated linear voltage post regulator. The IC regulates an input voltage

V

range of 2.7 V ≤

V

precision of

±2 %. The TLS208D1 is especially designed for applications with a permanent connection to

preregulators like DCDC converters. The device is available in the small surface mounted PG-DSO-8 (Exposed

Pad) package. In addition to the enable functionality, the feature set includes a reset with an adjustable reset

threshold. This threshold can be modified by an external resistor divider. 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. The TLS208D1 can be also used in all other applications requiring a stabilized voltage of 0.8 V to 5.25 V.
