The AZ1084D-ADJTRG1 voltage regulator is a high performance, low dropout (LDO) regulator from the PMIC - Voltage Regulators - Linear series of products. It features a very low dropout voltage of 0.2V, an adjustable output voltage of 1.2V to 12V, and a low quiescent current of 20µA. The AZ1084D-ADJTRG1 is capable of providing up to 1A output current and is well-suited for portable applications, such as cellphone power supply.

Unlike its predecessors, the AZ1084D-ADJTRG1 is capable of directly powering audio power amplifiers and Bluetooth modules, as well as supporting a wide Vin range from 2.2V to 12V. It also has excellent transient performance and high PSRR, making it an ideal choice for portable applications.

The AZ1084D-ADJTRG1 voltage regulator has a working principle which is built on what is known as an LDO regulator. This type of regulator works by having an input on one side of the device, usually referred to as the supply rail, and an output on the other, referred to as the load/output rail. A small amount of current from the supply rail is fed into a voltage reference, which is used to set the output voltage level. The output voltage generated by the load rail is then regulated to the reference voltage by changing the amount of current allowed to pass through the load rail. This serves to maintain the output voltage at a constant level despite variations in the supply rail voltage.

The AZ1084D-ADJTRG1 voltage regulator is an adjustable device, meaning that it can be adjusted to suit a wide range of applications. It features an adjustable output voltage range of 1.2V to 12V with a resolution of 0.2V, and can be set with very high precision depending on the application requirements. The device also features an adjustable mode, where the output voltage can be adjusted via a resistor divider network.

In addition to the adjustable output voltage, the AZ1084D-ADJTRG1 voltage regulator also features an adjustable power-on threshold voltage, which is typically set at 0.8V. This sounds like a low threshold voltage, meaning that the circuit can be powered up from as low as 0.8V without the need for additional components. This makes the device ideal for portable applications, ensuring reliable power-up even when running on low power sources.

The AZ1084D-ADJTRG1 voltage regulator is a versatile device, which can be used in a wide range of applications. It is well-suited for portable applications such as cellphones, tablet PCs, digital cameras, and other device power supplies, as well as audio power amplifiers and Bluetooth modules. Furthermore, the adjustable output voltage, high current-voltage accuracy, and low quiescent current make the AZ1084D-ADJTRG1 an attractive option for a wide variety of applications.
