Infineon TLE4266-2G

The OPTIREG™ Linear TLE4266-2G 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（overline） pin. It is functional compatible to the TLE4266, but with a reduced quiescent current of <<1 μA in OFF mode and 40 μA in ON mode. The TLE4266-2G 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 PG-SOT223-4 package. It is pin compatible to the TLE4266G. 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 TLE4266-2G can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage V₁ up to 45 V is regulated to VQ = 5 V (TLE4266-2G) or VQ = 3.3 V (TLE4266-2GSV33) 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 ℃. A High level at the INH（overline） pin switches the regulator on.
