An input voltage up to 40 V is regulated to an adjustable or 5 V fixed voltage with a precision of ±2%. 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 TLE42764 can be also used in all other applications requiring a stabilized voltage between 2.5 V and 20 V. PG-TO252-5 Due to its very low quiescent current the TLE42764 is dedicated for use in applications permanently connected to VBAT. In addition the device can be switched off via the Enable input reducing the current consumption to less than 10 µA.

I 1 Input CI 2 4 3 GND *) Optional Figure 3 CQ TLE42764 EN e.g. KL 15 Output 5 Q for adjustable Voltage Regulator R 1*) *) VA Voltage Adjust R 2*) AES02046 Application Diagram A typical application circuit of the TLE42764 is shown in Figure 3. It shows a generic configuration of the voltage regulator, with the recommendable minimum number of components one should use. Theoretically, if there is no risk of high frequency noise at all, even the small input filter capacitor can be omitted. For a normal operation mode of the device the only required device is the output capacitor, for the TLE42764GV and the TLE42764DV additionally the resistor divider. However, depending on the application’s environment, additional components like an input buffer capacitor or a reverse polarity protection diode can be considered as well. Input Filter Capacitor A small ceramic capacitor (e.g. 100nF in Figure 3) at the device’s input helps filtering high frequency noise. To reach the best filter effect, this capacitor should be placed as close as possible to the device’s input pin. The input filter capacitor does not have an influence on the stability of the device’s regulation loop. Output Capacitor CQ The output capacitor is the only external component that is required in any case as it is a part of the device’s regulating loop. To maintain stability of this loop, the TLE42764 requires an output capacitor respecting the values given in “Functional Range” on Page 5. Adjusting the Output Voltage of Variable Output Regulators TLE42764GV, TLE42764DV The output voltage of the TLE42764GV and the TLE42764DV can be adjusted between 2.5 V and 20 V by an external resistor divider, connected to the voltage adjust pin VA. The pin VA is connected to the error amplifier comparing the voltage at this pin with the internal reference voltage of typically 2.5 V.

Take into consideration, that the accuracy of the resistors R1 and R2 adds an additional error to the output voltage tolerance.
