The BD7004NUX-E2 is a linear voltage regulator. It is a two-terminal, highly integrated N-channel MOSFET linear regulator, specifically designed for automotive applications. It features low quiescent current, low dropout voltage (<0.2 V), and high ripple rejection performance characteristics.

The linear regulator has become an essential component in many automotive applications where the connection voltage is widely varying and the stability of the system is critical. The BD7004NUX-E2 is capable of regulating the connection voltage down to a steady voltage, protecting the device connected to it from potential harm.

The BD7004NUX-E2 has a static power switch, a mode controller, and a comparator. The static power switch is composed of a MOSFET device and ultra-low resistance resistors and current sources. The power switch regulates the connection voltage by connecting it to ground. The mode controller provides the logic signals to control the static power switch. As the connection voltage changes, the comparator will detect the difference between the current voltage and the target voltage, and adjust the logic signals accordingly.

The BD7004NUX-E2 is especially suitable for applications that need a precise and stable output voltage, such as stepping motors, power windows, central locking systems, and other automotive safety related circuits. Additionally, its 1 μA low quiescent current makes it ideal for battery operated applications, as it conserves power.

BD7004NUX-E2 is highly integrated, with a built-in thermal protection circuit and overcurrent protection circuit. The overcurrent protection circuit uses a built-in current limit resistor, ensuring that the device won’t be damaged in the event that an excessive current is drawn from the output. The thermal protection circuit trips when the junction temperature of the device reaches a preset value, and restarts when the temperature drops below a reset value.

Overall, the BD7004NUX-E2 is an efficient and reliable linear voltage regulator that is specifically designed for automotive applications. Its low quiescent current, simple circuitry, and built-in protection features make it an ideal choice for a wide range of applications.
