5-V Low Drop Voltage Regulator

TLE 7274

Features

•

Output voltage 5 V ±2%

Ultra low current consumption: typ. 20µA

300 mA current capability

Very low-drop voltage

Short-circuit-proof

P-TO252-3-1

Suitable for use in automotive electronics

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 V_Q,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.

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,

P-TO263-3-1

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 V_BAT. 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.
