Data Sheet Rev. 2.3 2002-12-21 Circuit Description The control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control, working as a function of load current, prevents any over-saturation of the power element. The IC is additionally protected against overload, overtemperature and reverse polarity.

Application Information

In the TLE 4264-2 the output voltage is divided and compared to an internal reference of 2.5 V typical. The regulation loop controls the output to achieve an output voltage of 5 V with an accuracy of ± 3% at an input voltage range of 5.5 V < VI < 45 V. Fig. 4 shows a typical application circuit. For stability of the control loop the TLE 4264-2 output requires an output capacitor CQ of at least 10 µF with a maximum permissible ESR of 4 Ω. Tantalum as well as multi layer ceramic capacitors are suitable. 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 occuring due the input inductivity and the input capacitor. In the application circuit shown in Fig. 4 an additional electrolytic input capacitor of 470 µF is added in order to buffer supply line influences. This capacitor is recommended, if the device is sourced via long supply lines of several meters. The TLE 4264-2 can supply up to 150 mA. However for protection for high input voltage above 25 V, the output current is reduced (SOA protection). AES02871 TLE 4264-2 Output Q GND Ι µ 10 F Input 5.5 to 45 V 100 nF 470 F µ
