ADP1707ARDZ-0.75R7 is a linear voltage regulator from the PMIC (Power Management Integrated Circuit) product category of voltage regulators. It is a low power regulator with a maximum output current of 0.75A, low dropout voltage and excellent line and load regulation. This regulator is designed to power microcontrollers, sensors, and other small loads requiring low power.

The ADP1707ARDZ-0.75R7 is a three-terminal adjustable voltage regulator with a wide input voltage range of 3.0 V to 15 V and an adjustable output voltage between 1.25 V and 12 V. It has a wide range of operating temperature (-40°C to 105°C). It also has low quiescent current (100 μA) and low dropout performance (300 mV). The output noise is low (30 μVrms).

The ADP1707ARDZ-0.75R7 can be used in a wide range of applications such as computers, consumer electronics, telecom, industrial, automotive and medical. It is used in applications such as gadget chargers, DC-DC converters and battery-powered systems, computer peripheral voltage power supply, and power management for portable and handheld consumer electronics.

The working principle of the ADP1707ARDZ-0.75R7 is similar to other linear voltage regulators. It compares a regulated voltage reference against a feedback voltage and adjusts the output voltage accordingly. The output voltage is controlled and regulated by the active components (transistors and resistors) inside the regulator. This makes it possible to accurately regulate the output voltage to a predetermined level.

When the input voltage is higher than the set output voltage, the regulator will start to reduce the output current and limit the output voltage to the set value. The regulator has two essential operating modes, steady-state operating mode (the Vref voltage is lower than the feedback voltage) and active control mode (the Vref voltage is higher than the feedback voltage).

To protect the load, the regulator has an over-current protection which shuts down the output when the current exceeds a certain threshold level. It also has a thermal shutdown circuit to protect against damaging temperatures rising above 150°C. The ADP1707ARDZ-0.75R7 also has a soft-start feature to safeguard the output voltage from sudden inrush current.

The ADP1707ARDZ-0.75R7 is a low power linear regulator that can provide an adjustable output voltage from 1.25 V to 12 V. It has low quiescent current, low dropout voltage, and excellent line and load regulation. Its wide input voltage range, operating temperature range, and protection features make it an excellent solution for a wide range of applications requiring low power.
