Introduction

The BD18HC5WEFJ-E2 is a low drop out (LDO) linear voltage regulator from ROHM Semiconductor. This linear voltage regulator is designed to provide a constant voltage output from a 5V input source over a wide range of temperatures and conditions. The device features high-accuracy output, low noise, and fast transient response. The BD18HC5WEFJ-E2 is ideal for use in a variety of applications, including personal electronics, automotive, LED backlighting, and industrial applications.

Applications

The BD18HC5WEFJ-E2 is suitable for use in a wide variety of applications. The device is ideal for providing a constant voltage output in systems that require a high accuracy and fast transient response, such as sensitive electronics, industrial applications, automotive, communications, and LED backlighting. The device is capable of driving outputs up to 200mA, making it suitable for use in applications that require a relatively low current output.

Features and Benefits

The BD18HC5WEFJ-E2 offers a wide range of features and benefits. The device features a low quiescent current of 1.1mA, making it a suitable device for use in lower power systems. The device is RoHS compliant and offers an overcurrent protection feature which will shut down output current if the output current exceeds 200mA. The device features an ultra-low dropout voltage of 0.1V, ensuring less noise on the output. The device is capable of providing an accurate output voltage of 5.0V ±0.3V, making it ideal for use in precision applications. The device also features a fast transient response of 8us to ensure the output remains regulated even when the input voltage changes quickly.

Working Principle

The BD18HC5WEFJ-E2 is a linear voltage regulator. The device works by using an internal voltage reference to compare the input voltage to the output voltage. The voltage reference is set by the feedback resistor. When the input voltage is higher than the output voltage, the device begins to regulate the output voltage by sinking current from the output. When the input voltage is lower than the output voltage, the device will source current from the input to maintain the output voltage. Because the device operates in a linear manner, the input current will increase linearly as the output voltage is raised.

Conclusion

The BD18HC5WEFJ-E2 is a low drop out, linear voltage regulator from ROHM Semiconductor. The device features high accuracy output, low noise, and fast transient response, making it suitable for use in a wide variety of applications, including personal electronics, automotive, LED backlighting, and industrial applications. The device is RoHS compliant and offers an overcurrent protection feature which will shut down output current if the output current exceeds 200mA. The device is capable of providing an accurate output voltage of 5.0V ±0.3V, making it ideal for use in precision applications. The device works by using an internal voltage reference to compare the input voltage to the output voltage.
