• 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
the harsh environment of automotive applications.
P-TO263-5-1
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.
