It is specifically designed for low-power applications. It can provide stable voltage and current for a wide variety of applications from desktop PCs to networking equipment.

Application field

ADP1712AUJZ-1.15R7 is suitable for input voltage range from 4V to 30V and output voltage range from 0.8V to 20V. It can be used in a variety of applications such as audio amplifiers, microcontrollers, analog-to-digital converters, FPGAs, power supplies, LED drivers and other low-power electronic equipment. It is also ideal for systems that require high output stability and low noise.

Working Principle

The ADP1712AUJZ-1.15R7 is a linear voltage regulator, meaning that it utilizes resistive voltage dividers to convert an input voltage to a desired output voltage. The input voltage is adjusted with a feedback circuit based on the output voltage, allowing it to regulate the output voltage accurately.The internal architecture of the regulator consists of a voltage sense amplifier, a transistor, an output current limit circuit and an output voltage setting circuit. The voltage sense amplifier monitors the output voltage and compares it with the reference voltage. If the output voltage is too low, the transistor is turned on to increase the output current. When the output voltage is too high, the transistor is turned off to reduce the output current. This closed-loop operation of the regulator maintains the output voltage at a stable level.

Conclusion

The ADP1712AUJZ-1.15R7 is a high-performance and low-loss linear voltage regulator that is suitable for use in a wide range of low-power applications. It offers excellent accuracy and stability, as well as low noise and standby current. The internal architecture of the regulator allows for accurate control of the output voltage, ensuring a reliable and stable performance.
