Features

• Fixed output voltage 5.0 V or 3.3 V  Output voltage tolerance ≤ ±2%, ±3%  150 mA current capability  Very low current consumption  Low-drop voltage  Overtemperature protection  Reverse polarity proof  Wide temperature range  Suitable for use in automotive electronics  Inhibit Functional Description The TLE 4266-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It can be switched on and off by the INH pin. It is functional compatible to the TLE 4266, but with a reduced quiescent current of << 1 µA in OFF mode and 40 µA in ON mode. The TLE 4266-2 is especially designed for all applications that require very low quiescent current in ON and OFF mode. The device is available in the small surface mounted P-SOT223-4-7 package. It is pin compatible to the TLE 4266 G. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature. Of course the TLE 4266-2 can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage VI up to 45 V is regulated to VQ = 5 V (TLE 4266-2 G) or VQ = 3.3 V (TLE 4266-2 GSV33) with an accuracy of ±3%. For the 5 V device 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 to 150 °C. A High level at the INH pin switches the regulator on.

Data Sheet 7 Rev. 1.2, 2004-01-01 Figure 3 Measuring Circuit Circuit Description and Application Information In the TLE 4266-2 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 ±2% at an input voltage up to 45 V. The minimum required input voltage is VQ + Vdr with a drop voltage Vdr of max. 0.5 V (see “Typical Performance Characteristics” on Page 8 ) in case of the TLE 4266-2 G. The TLE 4266-2 GSV33 requires a minimum input voltage of 4.4 V. The TLE 4266-2 can supply up to 150 mA. However for protection reasons at high input voltage above 25 V, the maximum output current is reduced (SOA protection). Figure 3 shows a typical measuring circuit. For stability of the control loop the TLE 4266-2 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 measuring 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 TLE 4266-2 includes the Inhibit function. For a voltage above 3.5 V at the INH pin the regulator is switched on. TLE 4266-2 nF100470 µF Vi Input
