High Voltage-Input LDO Regulators for Harsh Environments

12th October 2006

Texas Instruments has introduced a family of high voltage-input low-dropout 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.

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.

The devices extend TI's extensive portfolio of LDO regulators that cover applications with output currents that range from microamp keep-alive circuits to 7.5-A telecom loads.

The TLE4275QKTTRQ1, TL750M05QKTTRQ1 and TL760M33QKTTRQ1 are available in volume from TI and its authorized distributors in automotive-qualified 3- and 5-pin D2PAK (KTT) packages.
