Introduction

adjourning from traditional linear regulator products, the ADP1711AUJZ-1.10R7 is a low power, high accuracy CMOS linear regulator, where the output voltage of this device is dependent on the input voltage and the output reference voltage. In such a way, the device can adapt some key parameters such as output voltage, input voltage, output current, output voltage accuracy, and temperature coefficient. This device is suitable for a wide range of application fields, including telecommunications, automotive, industrial, and medical applications.

Application Field

ADP1711AUJZ-1.10R7 is a fixed voltage linear regulator, so it can provide a fixed output voltage from its input voltage. Thusly, the linear regulator can be applied in telecommunication, automotive, industrial and medical application as a power supply which can deliver a fixed voltage as required. It also be used in high temperature, low power LED driver applications to ensure the LED brightness when the input voltage changes. Lastly, the device can be used in post processing of image sensors and imaging applications, supplying a low noise voltage to the image sensor.

Working Principle

The ADP1711AUJZ-1.10R7 is a low power, high accuracy CMOS linear regulator which is designed to work on a maximum of 4.5V input voltage and 10mA output current. The output voltage of this device is regulated by a reference voltage which is applied to the REF pin. The regulator starts to work when the voltage at the REF pin is equal to the ground reference voltage. Upon increasing the voltage at the REF pin, The output voltage of the device increases by a certain amount which is dependent on the input voltage. The internal arrangement of the device is such that it uses an NMOS in series with a PMOS transistor which produces a very low off-state current. The bottom transistor’s gate is connected with the input voltage, and the top transistor’s gate is connected with the REF pin. When the voltage at the REF pin is equal to the ground reference voltage, the off-state current of the regulator is minimized, thus providing a low-power solution with high accuracy.

Conclusion

In conclusion, the ADP1711AUJZ-1.10R7 is a low power, high accuracy CMOS linear regulator that is ideal for a wide variety of applications, including telecommunications, automotive, industrial, and medical applications. Its output voltage is regulated by the voltage applied to the REF pin, and its internal schematic provides a low-power solution with high accuracy.
