Functional Description
The TLE 7274 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-TO263-3-1
Therefore it is protected against overload, short circuit
and over temperature conditions. Of course the
TLE 7274 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. 20µA the TLE 7274 is dedicated for use in applications permanently
connected to VBAT. 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 7274. A mV-range output noise
on the TLE 7274 caused by the charge pump operation is unavoidable due to the ultra
low quiescent current concept.
