Description
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 with a
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.
The input capacitor CI is recommended for compensating line influences. The output capacitor CQ is necessary
for the stability of the regulating circuit. Stability is guaranteed at values specified in “Functional Range” on
Page 8 within the whole operating temperature range.
