It is designed to supply e.g. microprocessor systems under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against overload, short circuit and reverse polarity. At overtemperature the regulator is automatically turned off by the integrated thermal protection circuit. Input voltages up to 40 V are regulated to VQ,nom = 3.3 V (V33 version) or 5.0 V (V50 version). The output is able to drive a load of more than 30 mA while it regulates the output voltage within a 4% accuracy. To save energy the device can be switched in stand-by mode via an inhibit input which causes the current consumption to drop below 5 mA.

V Q ,nom + 0.5V to 45V CΙ 100 nF Inhibit Ι 3 4 Q 3.0V / 3.3V / 5.0V TLE 4296-2G INH CQ 4.7 μF e.g. TDK C3216X7R1C475M 1 2,5 GND AES02313_4296-2 Figure 3 Application Diagram In the TLE4296-2 the output voltage is divided and compared to an internal reference of 2.5 V typical. The regulation loop controls the output to achieve a stabilized output voltage. Figure 3 shows a typical application circuit. In order to maintain the stability of the control loop the TLE4296-2 output requires an output capacitor CQ of at least 3.3 μF with a maximum permissible ESR of 2 Ω. It is recommended to use a multi layer ceramic capacitor for CQ, e.g. the TDK C3216X7R1C475M with a nominal capacitance of 4.7 μF. Aluminum electrolytic as well as tantalum capacitors do not cover the required ESR range over the full operating temperature range of Tj = -40 °C to +150 °C. At the input of the regulator an input capacitor is necessary for compensating line influences (100 nF ceramic capacitor recommended). A resistor of approx. 1 Ω in series with CI, can damp any oscillation occurring due the input inductivity and the input capacitor. If the regulator is sourced via long input lines of several meters it is recommended to place an additional electrolytic capacitor ≥ 47 μF at the input.
