TI Designs High Voltage-Input LDO Regulators for Harsh Environments

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.

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

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