TI Introduces High Voltage-Input LDO Regulators for Harsh Environments

Automotive-Qualified Devices Support Wide Input Range up to 45 V, Reduce External Component Count

DALLAS (October 11, 2006) -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a family of high voltage-input low-dropout (LDO) linear regulators designed to withstand the requirements for harsh operating environments. The new devices offer a wide input voltage range of up to 45 V, providing transient protection for applications such as automotive body controllers, instrument clusters, automotive audio and telematics (www.ti.com/sc06192).

The TLE4275QKTTRQ1, TL750M05QKTTRQ1 and TL760M33QKTTRQ1 are the first devices from TI to provide a direct connection to the vehicle battery with the ability to withstand load-dump transient conditions, reducing the number of external components needed to protect the LDO. Output stability has been optimized for typical automotive applications and low-cost capacitors.

Additional Key Features

o 450-750 mA maximum rated output currents
o Load-Dump, thermal shutdown and over-voltage protection
o 3.3 V, 5 V and 8 V fixed-output-voltage versions
o Power-on and under-voltage reset (TLE4275-Q1)
o Industry-standard TO-263 (D2PAK) packages for maximum power dissipation
