The RS3011-Q1 device is designed for automotiveapplications with a 45V load dump. The device caneither be used as one tracking low-dropout (LDO)regulator or voltage tracker to build one closed powerloop for off-board sensors with an onboard mainsupply. The output of the device is accuratelyregulated by a reference voltage at the ADJ pin.To provide an accurate power supply to the off-boardmodules, the device offers a 4mV ultralow trackingtolerance between the ADJ and FB pins acrosstemperature. The back-to-back PMOS topologyeliminates the need for an external diode underreverse polarity condition. The RS3011-Q1 devicealso includes thermal shutdown, inductive clamp,overload, and short-to-battery protection to preventdamage to onboard components during extremeconditions.
