TPS7B4259-Q1 Low-Dropout (LDO) Regulator

Texas Instruments TPS7B4259-Q1 Low-Dropout (LDO) Regulator is an automotive, 150mA, 40V voltage-tracking regulator with independent enable and power good. This device is a monolithic, integrated LDO voltage tracker designed to reliably provide power to off-board sensors with a wire harness, even in harsh automotive environments. The TPS7B4259-Q1 comes with integrated protection features against fault conditions and protection against reverse polarity. This device features a topology consisting of two back-to-back P-channel MOSFETs. The TPS7B4259-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 TPS7B4259-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.
