Working Principle

AZ1117H-1.2TRG1 uses linear regulator technology, that is to say that it uses a feedback loop to regulate the voltage output. In this feedback loop, a sensing voltage is compared to a reference voltage, and if the two voltages are not equal, the output of the chip is adjusted accordingly by adjusting either the internal series resistor, the base current on the pass transistor, or both. The loop will eventually reach a stable state when the two voltages match above a certain amount. This results in a very precise and stable output voltage for the application.

Conclusion

AZ1117H-1.2TRG1 is a reliable linear voltage regulator chip that offers an adjustable output range of 1.2V to 10V and supports input voltages up to 20V. This makes the device quite versatile and suitable for a wide range of power supply applications. In addition, its linear regulation technology ensures precision and stability, making it an ideal solution for critical applications in the telecommunications, automotive, and industrial fields.
