The ADP3367ARZ is an energy-efficient, low voltage linear regulator from Analog Device’s Standard LDO family. It accurately regulates VOUT at 1.8 V over a wide input range. The device features over current and thermal shutdown protection, making it an ideal choice for battery powered consumer devices.

The ADP3367ARZ is a low dropout (LDO) voltage regulator with a voltage reference accuracy of +/- 0.8%. This allows the device to maintain a stable voltage output over a wide input voltage range. Its power-saving Integrated Current Limit (ICL) prevents excessive quiescent current during light-load or no-load operation.

The ADP3367ARZ has a wide input voltage range of 1.8 to 7 V, and an adjustable output voltage range of 1.3 to 5.5 V. With its high power supply rejection ratio (PSRR), the device is excellent for use in applications sensitive to supply voltage fluctuations. In addition, the ADP3367ARZ features over current and thermal shutdown protection to ensure safe use of the device.

The ADP3367ARZ can be used in many different applications. It is designed for battery powered consumer devices, including cell phones and digital cameras, where low power consumption is critical. It is also suitable for space-restricted applications such as mobile device accessories and PC add-on cards.

The ADP3367ARZ linear regulator works based on a typical feedback topology. The device has a comparator, an error amplifier, a voltage reference and an output stage.

The comparator is used to detect the output voltage. When the voltage drops below the reference voltage, the comparator triggers the error amplifier.

The error amplifier amplifies the difference between the actual output voltage and the reference voltage, resulting in a correction signal. This signal is then applied to the output stage.

The output stage contains a pass transistor, which is connected to the voltage reference. The voltage reference determines the output voltage level. The pass transistor is controlled by the correction signal from the error amplifier. By varying the current through the pass transistor, the output voltage of the regulator is regulated.

To sum up, the ADP3367ARZ is a low voltage linear regulator from Analog Device’s Standard LDO family. With its wide input range, high power supply rejection ratio (PSRR) and over current and thermal shutdown protection, it is designed for battery powered consumer devices. The voltage regulator works based on a typical feedback topology. The device has a comparator, an error amplifier, a voltage reference and an output stage.
