TPS7B4256-Q1 Voltage-Tracking LDO Regulator

Texas Instruments TPS7B4256-Q1 Voltage-Tracking Low-Dropout (LDO) Regulator is available in 8-pin SOIC and HSOIC packages. The TPS7B4256-Q1 is designed to provide power supply to off-board sensors in an automotive environment. Because of the high risk of failure in cables that deliver off-board power, the device has integrated protection features against fault conditions such as short to battery, reverse polarity, output short to ground (current limit), and overtemperature (thermal shutdown). The device incorporates a back-to-back PMOS topology that eliminates the need for an external diode that is otherwise required to help protect against fault conditions that result in reverse current flow. The Texas Instruments TPS7B4256-Q1 is designed to handle a 45V (absolute maximum) input voltage and survive the automotive load dump transient conditions.
