120 mA, 40 V low-dropout voltage regulator
The NEX94212-Q100 device is a Low-Dropout (LDO) linear regulator with fixed output voltage of 5 V which can supply loads up to 120 mA. The device supports a wide input voltage range from 4 V to 40 V (up to 45 V transient) to withstand cold-cranking and load-dump transient conditions.
The device integrates multiple protection features. When configured as a power supply for off-board components (e.g., sensors) with external cables, the built-in short-to-battery and reverse polarity protections (-42 V) safeguard the system against harness failures. The device employs a back-to-back PMOS topology to block reverse current without requiring an external diode. The device also supports current limit protection to protect against output short-to-ground or overload conditions that will eventually trigger thermal shutdown if shorting or overloading lasts long.
The device switches to standby mode by pulling down the EN pin, which enables an ultra-low shutdown current of 0.65 µA typical to extend battery life. It operates across an ambient temperature range from -40 °C to 125 °C, and a junction temperature range from -40 °C to 150 °C. Additionally, this device is available in SOT223 package.

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.
