It is the 1-to-1 replacement product for the TLE4266-2. It is functional compatible to the TLE4266, but has a reduced quiescent current of typ. 40 A. The TLE42664 is especially designed for applications requiring very low standby currents, e.g. with a permanent connection to the car's battery. It can be disabled/enabled by the integrated EN pin. The device is available in the small surface mounted PG-SOT223-4 package and is pin compatible to the TLE4266-2 and the TLE4266. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and overtemperature conditions by the implemented output current limitation and the overtemperature shutdown circuit. The TLE42664 can be also used in all other applications requiring a stabilized 5 V voltage. An input voltage up to 45 V is regulated to VQ,nom = 5 V with a precision of 3 %. An accuracy of 2 % is kept for load currents up to 50 mA. A logical "HIGH" at the ENABLE pin enables the device.

Ignition DI <45V C I2 C I1 10F 100nF Regulated I Q I Q Output Voltage Current Limitation EN CQ Enable Bandgap Reference Temperature Shutdown 10 F (ESR<2) Load ( e.g. Micro Controller) GND GND Figure 3 Application Diagram 6.2 Selection of External Components 6.2.1 Input Pin The typical input circuitry for a linear voltage regulator is shown in the application diagram above. A ceramic capacitor at the input, in the range of 100 nF to 470 nF, is recommended to filter out the high frequency disturbances imposed by the line e.g. ISO pulses 3a/b. This capacitor must be placed very close to the input pin of the linear voltage regulator on the PCB. An aluminum electrolytic capacitor in the range of 10 F to 470 F is recommended as an input buffer to smooth out high energy pulses, such as ISO pulse 2a. This capacitor should be placed close to the input pin of the linear voltage regulator on the PCB. An overvoltage suppressor diode can be used to further suppress any high voltage beyond the maximum rating of the linear voltage regulator and protect the device against any damage due to over-voltage. The external components at the input are not mandatory for the operation of the voltage regulator, but they are recommended in case of possible external disturbances. 6.2.2 Output Pin An output capacitor is mandatory for the stability of linear voltage regulators. The requirement to the output capacitor is given in "Functional Range" on Page 5. The graph "Region Of Stability: Output Capacitor's ESR ESR(CQ) versus Output Current IQ" on Page 9 shows the stable operation range of the device. Data Sheet 10 Rev. 1.1, 2014-07-03 TLE42664 Application Information TLE42664 is designed to be stable with extremely low ESR capacitors. According to the automotive environment, ceramic capacitors with X5R or X7R dielectrics are recommended. The output capacitor should be placed as close as possible to the regulator's output and GND pins and on the same side of the PCB as the regulator itself. In case of rapid transients of input voltage or load current, the capacitance should be dimensioned in accordance and verified in the real application that the output stability requirements are fulfilled. 6.3 Thermal Considerations Knowing the input voltage, the output voltage and the load profile of the application, the total power dissipation can be calculated: (1) PD = ( VI - VQ ) x IQ + VI x Iq with * * * * * PD: continuous power dissipation VI: input voltage VQ: output voltage IQ: output current Iq: quiescent current The maximum acceptable thermal resistance RthJA can then be calculated: (2) T j, max - T a R thJA, max = --------------------------PD with * * Tj,max: maximum allowed junction temperature Ta: ambient temperature Based on the above calculation the proper PCB type and the necessary heat sink area can be determined with reference to the specification in "Thermal Resistance" on Page 6. Example Application conditions: VI = 13.5 V VQ = 5 V IQ = 50 mA Ta = 105 C Calculation of RthJA,max: PD = (VI - VQ) * IQ + VI * Iq = (13.5 V - 5 V) * 50 mA + 13.5 V * 4 mA = 0.425 W + 0.054 W = 0.479 W Data Sheet 11 Rev. 1.1, 2014-07-03 TLE42664 Application Information RthJA,max = (Tj,max - Ta) / PD = (150 C - 105 C) / 0.479 W = 93.9 K/W As a result, the PCB design must ensure a thermal resistance RthJA lower than 93.9 K/W. By considering TLE42664G (PG-SOT223-4 package) and according to "Thermal Resistance" on Page 6, at least 300 mm heatsink area is needed on the FR4 1s0p PCB, or the FR4 2s2p board can be used. 6.4 Reverse Polarity Protection TLE42664 is self protected against reverse polarity faults and allows negative supply voltage. External reverse polarity diode is not needed. However, the absolute maximum ratings of the device as specified in "Absolute Maximum Ratings" on Page 5 must be kept. The reverse voltage causes several small currents to flow into the IC hence increasing its junction temperature. As the thermal shut down circuitry does not work in the reverse polarity condition, designers have to consider this in their thermal design.
