Introduction
1 Introduction
This document describes the demoboard for the TLS715B0NAV50 and explains its functionality. It includes a
brief summary of the used passive components, as well as a short explanation on how to use the demoboard
currectly. The description of the TLS715B0NAV50 is not subject of this document. Specifications and
parameters for the device shall be taken form the corresponding datasheet.
Table 1 provides an overview of the family members of TLS710/TLS715B0 voltage regulators.

1.1 General Description
The OPTIREG™ Linear TLS715B0NAV50 is a low dropout linear voltage regulator for load current up to 150 mA.
An input voltage of up to 40V is regulated to V
The TLS715B0NAV50, with a typical quiescent current of 36 µA, is the ideal solution for systems requiring very
low operating current, such as those permanently connected to the battery.
It features a very low dropout voltage of 180 mV, when the output current is less than 100 mA. In addition, the
dropout region begins at input voltages of 4.0 V (extended operating range). This makes the TLS715B0NAV50
suitable to supply automotive systems with start-stop requirements.
The device can be switched on and off by the Enable feature.
In addition, the new fast regulation concept of the TLS715B0NAV50 requires only a single 1µF output capacitor
to maintain stable regulation.
The device is designed for the harsh environment of automotive applications. Therefore, standard features
like output current limitation and overtemperature shutdown are implemented and protect the device
against failures like output short circuit to GND, over-current and over-temperature. The TLS715B0NAV50 can
be also used in all other applications requiring a stabilized 5 V supply voltage.
