5-V Low Drop Voltage Regulator
TLE 7276
Features * * * * * * * Output voltage 5 V 2% Ultra low current consumption: typ. 20 A 300 mA current capability Inhibit input Very low-drop voltage Short-circuit-proof Suitable for use in automotive electronics
P-TO252-5-1
Functional Description The TLE 7276 is a monolithic integrated low-drop voltage regulator for load currents up to 300 mA. An input voltage up to 42 V is regulated to VQ,nom = 5.0 V with a precision of 2%. The sophisticated design allows to achieve stable operation even with ceramic output capacitors down to 470 nF. The device is designed for P-TO263-5-1 the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and overtemperature conditions. Of course the TLE 7276 can be used also in all other applications, where a stabilized 5 V voltage is required. Due to its ultra low stand-by current consumption of typ. 20 A the TLE 7276 is dedicated for use in applications permanently connected to VBAT. The regulator can be shut down via an Inhibit input. An integrated output sink current circuitry keeps the voltage at the Output pin Q below 5.5 V even when reverse currents are applied. Thus connected devices are protected from overvoltage damage. For applications requiring extremely low noise levels the Infineon voltage regulator family TLE 42XY and TLE 44XY is more suited than the TLE 7276. A mV-range output noise on the TLE 7276 caused by the charge pump operation is unavoidable due to the ultra low quiescent current concept.

Application Diagram
An input capacitor is necessary for damping line influences. A resistor of approx. 1 in series with CI, can damp the LC of the input inductivity and the input capacitor. In contrast to most low drop voltage regulators the TLE 7276 only needs moderate capacitance at the output to assure stability of the regulation loop. This offers more design flexibility to the circuit designer providing for cost efficient solutions. The TLE 7276 requires a ceramic output capacitor of at least 470 nF. In order to damp influences resulting from load current surges it is recommended to add an additional electrolytic capacitor of 4.7 F to 47 F at the output as shown in Figure 3.
