AZ1117D-1.8TRE1 Application Field and Working Principle

AZ1117D-1.8TRE1 is a three-terminal linear Voltage Regulator from PMIC. It is specially designed to provide a variable output voltage from 0.8V to 13.2V. It delivers a maximum output current of up to 250mA.

Application Field

The AZ1117D-1.8TRE1 is widely used for applications related to mobile devices, automotive, consumer electronics, industrial, and telecom where adjustable output voltage is required. It performs very well in energy consuming scenarios with low distortion. It has excellent power conversion efficiency up to 83%, which makes it suitable for low consumption applications. On top of that, as a three-terminal linear Voltage Regulator, it is robust and failure-shielded against overvoltage resulting in a stable supply voltage.

Working Principle

The basic principle of AZ1117D-1.8TRE1 is to provide an adjustable output voltage of 0.8V to 13.2V. It can function as both voltage regulator and current limit protection. When the input voltage is greater than the output voltage, it regulates the current by means of an internal transistor so that the voltage drop across the transistor equals the difference between the input and output voltage. In the situation when the input voltage varies while the output voltage stays the same, AZ1117D-1.8TRE1 adjusts its output current to maintain the same output voltage. In the case of overvoltage, it shuts off the respective output currents and protects the device from electrical damages.

Conclusion

The AZ1117D-1.8TRE1 is a three-terminal linear Voltage Regulator from PMIC, specially designed for applications related to mobile devices, automotive, consumer electronics, industrial, and telecom providing variable output voltage from 0.8V to 13.2V. It has excellent power conversion efficiency up to 83% and very good protection features against overvoltage. The principle of its operation is to regulate the current by means of an internal transistor and maintain the same output voltage in case of input voltage changing.
