AZ1117CR-1.8TRG1

The AZ1117CR-1.8TRG1 is a linear voltage regulator powered by an Internal + 1.8 V adjustable output voltage. It offers a low dropout voltage, low output noise, and low quiescent current. This device features a wide range of features, including overload protection, over temperature protection, and output under-voltage protection. The device also features a built-in current-mode control function with a switch set to low power or high power. It also has a current-limiting protection to prevent over-current and a temperature-limiting protection to protect against excessive heat.

The AZ1117CR-1.8TRG1 is often used in consumer electronics and automotive applications. It is commonly used to provide an adjustable power supply from 4.5V-18V to 3.3V or an distributed power supply to multiple consumer electronic components. It is also used to power motors, LCD displays, and other consumer electronics applications. It is designed for minimal power losses and noise, allowing for reliable and efficient operation.

The working principle of the device is based on a linear regulating process. This regulation process is divided into two parts- voltage dropout and current limiting. The basic principle is to reduce the input voltage by a predetermined amount, and the current limiting is then used to regulate the output. The internal stacked voltage reference is regulated by an external, or an internal resistor or potentiometer. This reference voltage is then compared to the input, triggering a series of events to ensure an accurate and stable output.

The AZ1117CR-1.8TRG1 also features a built-in Thermal Shutdown protection. This helps to ensure that the voltage regulator remains within an acceptable temperature range. When the internal temperature of the device reaches a predetermined level, the internal thermal detection circuit triggers a shutdown, preventing the device from damage due to extreme temperatures.

The AZ1117CR-1.8TRG1 is a versatile linear voltage regulator, ideal for applications where efficiency and reliability are important. It can provide reliable and efficient power for consumer electronics, automotive, and industrial applications. With its wide range of features, it can provide protection against excessive heat, over-currents, and more, allowing for a reliable and safe operation for any application.
