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 µA 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
Input, Output
An input capacitor is necessary for damping line influences. A resistor of approx. 1 Ω 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 µF to 47 µF at the output as shown in Figure 3.
