The AZ1084D-1.8TRG1 from Nexperia is one such Voltage regulator which is classified under PMIC - Voltage Regulators – Linear. This regulator is a two terminal, low drop-out (LDO) voltage regulator with an operating temperature range from 0°C to 85°C and an input voltage range from 1.8V to 5.5V. Its output voltage range is fixed at 1.8V with a tolerance range of ±1.0%.

The AZ1084D-1.8TRG1 has various features and characteristics which makes it highly useful in various application areas. It is specifically designed to deliver stable voltage supply in battery powered equipment to ensure the uninterrupted operation of digital equipment and prevent voltage irregularities or fluctuations. It can be used in automotive applications, industrial electronic systems, consumer electronics, medical applications, energy related equipment and industrial/commercial applications.

The AZ1084D-1.8TRG1 has a high accuracy of ±1.0% which makes it appropriate for use in applications where precision is of extreme importance. Additionally, it offers high power supply rejection of 53dB at 1kHz and an output current of about 100mA and maximum current of up to 200mA, making it ideal for use in low power applications. The quiescent current of this device is also very low at 3.2µA, enabling it to save power and work with increased efficiency in most systems. It also has short circuit protection and can work in low drop-out mode.

The working principle of the AZ1084D-1.8TRG1 can be described as follows. It works by taking a DC input voltage and reducing it to a fixed voltage output. This is achieved by passing the DC input voltage through the internal pass transistor of the regulator. The output voltage is then regulated by controlling the base current of the internal transistor. The base current is in turn controlled by a series of voltage and current sensing circuits that constantly monitor the output voltage and adjust the base current as needed.

In addition, the AZ1084D-1.8TRG1 has a soft-start feature that ensures smooth startup of the device. The device also has an in-rush current limiter that is used to protect it from high input current spikes when the device is powered-on. It also has over-voltage protection that prevents the device from being damaged when a higher voltage is applied to it and short-circuit protection that ensures the device is not damaged if a short-circuit occurs.

Thus, it can be concluded that the AZ1084D-1.8TRG1 from Nexperia is an ideal LDO voltage regulator for low-power applications that require a precise and stable output voltage. This device has a wide operating temperature range, high power supply rejection, low quiescent current and various protection features that ensure its operation is safe and efficient.
