TPS7B4258-Q1 Low-Dropout (LDO) Regulator

Texas Instruments TPS7B4258-Q1 LDO Regulator is an automotive 150mA, 40V, voltage-tracking LDO with a 6mV tracking tolerance. This regulator is designed to reliably provide power to off-board sensors via a wire harness, even in a harsh automotive environment. The TPS7B4258-Q1 comes with integrated protection features against fault conditions and protection against reverse polarity. This device incorporates a topology containing two back-to-back P-channel MOSFETs. The TPS7B4258-Q1 regulator device is designed to handle a 45V (absolute maximum) input voltage and survive the automotive load dump transient conditions. This LDO regulator provides a protective buffer for the ADC and MCU against fault conditions, while securely transferring power to the off-board sensors. The TPS7B4258-Q1 regulator is available in the HSOIC (DDA) low thermal resistance (R_θJA = 48°C/W) 8-pin package. This regulator is ideal for powertrain pressure sensors, powertrain temperature sensors, powertrain exhaust sensors, powertrain fluid concentration sensors, Body Control Modules (BCM), zone control module, and HVAC control modules.
