5-V Low Drop Fixed Voltage Regulator TLE 4264-2 Features Output voltage tolerance 3% (2% up to 50 mA) 150 mA current capability Low-drop voltage Very low current consumption: 40 A Overtemperature protection Short-circuit proof Suitable for use in automotive electronics Reverse polarity proof P-SOT223-4 Green Product (RoHS compliant) AEC Qualified Functional Description The TLE 4264-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It is functional compatible to the TLE 4264, but has a reduced quiescent current of typ. 40 A. The TLE 4264-2 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 TLE 4264. 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 TLE 4264-2 can be used in all other applications, wherever a stabilized voltage is required. An input voltage V in the range of 5.5 V < V < 45 V is regulated to V = 5 V with an I I Q,nom 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 T = -40 to 150 C. j Type Package TLE 4264-2 G PG-SOT223-4 Data Sheet 1 Rev. 2.6, 2008-03-10 TLE 4264-2 GND 4 123 GND Q AEP02868 Figure 1 Pin Configuration (top view) Table 1 Pin Definitions and Functions Pin Symbol Function 1I Input voltage block to ground directly with a ceramic capacitor 2, 4 GND Ground 3Q 5-V output voltage block to ground with a capacitor C 10 F, ESR 4 Q Data Sheet 2 Rev. 2.6, 2008-03-10
