Working Principle
The AZ1117ID-1.2TRG1 is a low-dropout (LDO) linear voltage regulator with a dropout voltage of typically 0.23 V. It works by using bipolar transistors to create an output voltage that is regulated within small deviations of the desired value. This is accomplished by using a circuit referred to as an ‘error amplifier’, which compares the output voltage to a reference voltage, and adjusts the output voltage based on the difference between the two.In a typical linear regulator circuit, the error amplifier is placed between the voltage source and the load. The output voltage is compared to the reference voltage and a correction current is sent to the load. This correction current is provided by the error amplifier in order to keep the output voltage within the small tolerance of the desired value.Moreover, the device also has a built-in current limit of 1.2A and thermal shutdown feature to protect it against high-current surges and overtemperature conditions. The reset pin can be used to monitor the output impedance and reset the system in case of excessive current.Conclusion
In conclusion, the AZ1117ID-1.2TRG1 is an ideal solution for automotive and other applications requiring a low-dropout, low-noise linear regulator capable of supplying up to 1.2A of output current. The device includes various protection features for improved reliability and performance, such as current limit, thermal shutdown and reverse current protection. Its small size and low quiescent current make it perfect for applications where power, efficiency, and space savings are all key requirements.The specific data is subject to PDF, and the above content is for reference
