NEX91X30-Q100
Automotive 300 mA, 40 V tracking LDO with 5 mV tolerance
The NEX91x30-Q100 is a Low-Dropout (LDO) voltage-tracking regulator with high tracking accuracy 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, 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 EN/ADJ pin with an accuracy of ±5 mV over the specified temperature range for loads up to 300 mA. 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 EN/ADJ 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 power-good (PG) output indicates an over voltage or under voltage condition of the tracking output.
The device operates across a temperature range from -40 °C to 125 °C ambient and -40 °C to 150 °C junction. It is available with thermal enhanced package SOT8063-2 (HSO8).
