The ADP170AUJZ-2.8-R7 is a linear voltage regulator from the power management integrated circuit (PMIC) family used to provide fixed voltage regulation at a specific output voltage. Typical applications for this type of regulator are for mobile devices, such as mobile phones, tablets, and laptop computers. It is also used in automotive and industrial applications, as well as embedded systems, controllers, power supplies, and other computing devices.

Leveraging the latest technology in low-power, high-efficiency designs, this linear voltage regulator is capable of providing a regulated output voltage up to 2.8V. It has an adjustable surge current, allowing it to accept supply voltages up to 6V with a wide input range. Additionally, it features a 100µA shutdown current and an adjustable current limit, making it highly efficient and reliable under a wide range of operating conditions.

The working principle of the ADP170AUJZ-2.8-R7 is to use a linear voltage regulator, which is essentially an operational amplifier, to create a stable output voltage from an unregulated input voltage. The linear voltage regulator receives an input supply voltage and a reference voltage, which is typically connected to ground. It uses the reference voltage to compare against its input supply voltage, and then it increases or decreases its output voltage to maintain the ideal regulated voltage. The regulator accomplishes this by controlling the amount of power it passes on to the output. In most cases, the output voltage is regulated to a fixed value and constantly monitored by the regulator.

The ADP170AUJZ-2.8-R7 is designed with a very low-power consumption in mind, making it ideal for power-sensitive applications. It manages a low quiescent current of only 0.8mA, and has a wide operating temperature range from -40°C to +85°C. It is designed to provide a constant output voltage with a maximum load current of up to 36mA and a low dropout voltage of 150mV. Additionally, it has an adjustable current-limit feature which allows the device to protect itself from out of range supply voltages.

In summary, the ADP170AUJZ-2.8-R7 is an ideal choice for applications in which low power consumption is important. With its wide input range and multiple protection features, it is suitable for a variety of applications in which the output voltage needs to remain stable. The device is well suited for a variety of mobile, automotive, and industrial applications, as well as embedded systems, controllers, power supplies, and other computing systems.
