Description The OPTIREG™ Linear TLE4264-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It is functional compatible to the TLE4264, but has a reduced quiescent current of typ. 40 µA. The TLE4264-2 is especially designed for all applications which require very low quiescent currents. The device is available in the small surface mounted PG-SOT223-4 package. The device is pin compatible to the TLE4264. The regulator is designed to supply microprocessor systems under the severe condition of automotive applications and is therefore equipped with additional protection against overload, short-circuit and overtemperature. Of course the TLE4264-2 can be used in all other applications, wherever a stabilized voltage is required. An input voltage VI in the range of 5.5 V < VI < 45 V is regulated to VQ,nom = 5 V with an accuracy of ±3%. An accuracy of ±2% is kept for a load current range up to 50 mA. The device operates in the temperature range of Tj = -40°C to 150°C.

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. In the TLE4264-2 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. Figure 3 shows a typical application circuit. For stability of the control loop the TLE4264-2 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 occurring due the input inductivity and the input capacitor. In the application circuit shown in Figure 3 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 TLE4264-2 can supply up to 150 mA. However for protection for high input voltage above 25 V, the output current is reduced (SOA protection).
