TPS7B4260-Q1 Low-Dropout (LDO) Voltage Tracker

Texas Instruments TPS7B4260-Q1 Low-Dropout (LDO) Voltage Tracker is designed to reliably provide power to off-board sensors with a wire harness, even in harsh automotive environments. In such severe operating conditions, the cables in the harness are potentially exposed to various fault conditions, increasing the risk of failure. Such conditions include short-to-ground, short-to-battery, and over-temperature. The TPS7B4260-Q1 comes with integrated protection features against each of these fault conditions, as well as protection against reverse polarity. The device incorporates a topology containing two back-to-back P-channel metal-oxide semiconductor field-effect transistors (MOSFETs). This PMOS topology eliminates the need for an external diode that is otherwise required to prevent reverse current flow. The high 300mA current rating of the device potentially allows a single tracker to power multiple off-board sensors simultaneously. The device is designed to handle a 45V (absolute maximum) input voltage and survive the automotive load dump transient conditions.
