Automotive 70 mA, 40 V tracking LDO with 5 mV tracking tolerance
The NEX91207-Q100 is a Low-Dropout (LDO) voltage-tracking regulator with a precise tracking tolerance of 5 mV (max) and excellent load and line transient responses. It is specifically designed to power off-board sensors in automotive applications such as power train systems, safety, and Body Control Modules (BCMs). The device supports a wide input voltage range from 4 V to 40 V (up to 45 V transient) to withstand cold-crank and load-dump transient conditions.
The device output tracks the reference voltage applied to the ADJ/EN pin with an accuracy of ±5 mV over the specified temperature range. The high tracking accuracy ensures a precise power supply for off-board sensors and modules, improving the performance of radiometric sensors such as pressure and position sensors.
The device switches to standby mode by pulling down the ADJ/EN pin, which enables an ultra-low shutdown current of 0.75 µA typical to extend battery life. The device integrates protection features such as battery reverse polarity protection (-42 V), output reverse current protection, output short-to-battery and ground protection, current limit, and thermal shutdown. These protections guard against the high risk of cable failures in an off-board power system.
The device operates across a temperature range from -40 °C to 125 °C ambient and -40 °C to 150 °C junction. It is available in two package options with different thermal resistance, including SOT8105-1 (SOT23-5S) and SOT8104-1 (SOT23-5).

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
