Introduction

The ADP1713AUJZ-1.15R7 is a voltage regulator manufactured by Analog Devices. It is a linear voltage regulator that provides a range of output voltages from 1.15 V to 10.0 V. It has an operating input voltage range of 3.3 V to 5.5 V and can provide up to 4 A of output current. The ADP1713AUJZ-1.15R7 offers excellent line and load regulation, as well as low-noise operation.

Application Field

The ADP1713AUJZ-1.15R7 is well-suited for use in a variety of applications, including personal electronics, embedded systems, and industrial applications. The device’s low-noise operation and low input-to-output voltage differential make it ideal for use in audio applications as well. The device is also well-suited for use in mobile applications, such as PDAs, smartphones, and tablet computers, due to its low quiescent current and small footprint. The device’s wide input voltage range also makes it well-suited for use in automotive applications. It can be used in applications where the power supply voltage can fluctuate from 3.3 V to 5.5 V, such as in vehicles with varying battery voltages due to changing engine speeds. The ADP1713AUJZ-1.15R7 is also well-suited for use in point-of-load (POL) power supplies, where its low output voltage offsets and low quiescent current make it ideal for providing ultra-low output voltage.

Working Principle

The ADP1713AUJZ-1.15R7 is an integrated linear voltage regulator that provides a regulated output voltage based on a reference voltage and an adjustable control voltage. It utilizes a bandgap reference to generate a constant reference voltage and an operational amplifier to regulate the output voltage. The device’s output voltage is adjusted using an external resistor divider network. The output voltage is then compared to the reference voltage, and an error signal is generated. This error signal is fed to the operational amplifier, which adjusts the output voltage by driving the output transistor’s base current. The output voltage is then regulated to the desired value. The ADP1713AUJZ-1.15R7 also features built-in thermal protection. If the device’s die temperature exceeds a certain threshold, the output is disabled to prevent damage to the device. The device’s over-temperature protection can also be disabled if desired. The device is also designed to withstand input voltage transients. It incorporates a built-in transient suppressor and over-voltage protection circuit that prevents damage to the device and allows for operation in harsh environments.

Conclusion

The ADP1713AUJZ-1.15R7 is a linear voltage regulator that provides a range of output voltages from 1.15 V to 10.0 V. It is well-suited for use in a variety of applications, including personal electronics, embedded systems, and automotive applications. The ADP1713AUJZ-1.15R7 utilizes an integrated bandgap reference and operational amplifier to regulate the output voltage and built-in thermal and over-voltage protection circuits to protect the device from damage.
