AZ1117CR-1.5TRG1 is a low power regulator with adjustable voltage output, which belongs to the category of PMIC (Power Management Integrated Circuit) - Voltage Regulators - Linear. This regulator integrated circuit, or IC, is designed to provide high performance and stable voltage regulation, while requiring minimal power by converting the higher input voltage to the specified output voltage. It is suitable for many applications such as easily locking clock sources, EPROMs, microcontrollers and memory chips, which require a precise 1.5 V output power supply voltage.

The AZ1117CR-1.5TRG1’s working principle is based on the linear regulators type, implying that the output current is equal to the input current, because there is not internal power switch or amplifier. The voltage regulator consists of a pass transistor which, with the help of a few other components, is able to maintain a steady low voltage at its output terminal. It achieves this by adjusting the control voltage as necessary to ensure a constant voltage level is maintained at the output. 

The output of the AZ1117CR-1.5TRG1 is connected to the external feedback resistor divider chain which calibrates the voltage at the output. The voltage comparator looks for the difference between the voltage at its non-inverting (positive) input and it’s inverting (negative) input and generates an error signal (the output voltage minus is set reference voltage).

This error signal is then sent to the error amplifier which in turn amplifies the error signal and sends it to the reference-voltage regulator. Here, this amplified error signal is used to adjust the reference voltage, which in effect changes the output voltage. The magnitude of the output voltage can then be adjusted by changing the feed-forward resistor divider and the resistor divider ratio.

The features of the AZ1117CR-1.5TRG1 makes it ideal for a wide range of applications that require a very precise output voltage with low power consumption. Its low output noise makes it suitable for powering noise-sensitive integrated circuits, while its short-circuit protection adds enhanced safety to the circuit. The AZ1117CR-1.5TRG1 can be used for a variety of projects: portable systems, battery chargers, instrumentation systems, data converters, laser diode drivers, embedded applications, and more.

In conclusion, the AZ1117CR-1.5TRG1 is a versatile PMIC - Voltage Regulators - Linear integrated circuit that is able to provide a precise and stable output voltage with low power consumption. Its adjustable voltage output and numerous features make it suitable for a wide range of projects and applications.
