AZ1117H-2.5TRE1 Application Field and Working Principle

Introduction

The AZ1117H-2.5TRE1 is a low-dropout linear voltage regulator produced by AZ Microelectronics. It provides a voltage stabilization function and further increases system reliability and stability. This product is ESDA-certified, so it has good electrostatic protection and is suitable for medical, automotive and industrial control systems. This product is supplied in a 7-pin SOP package and provides a large output current of 1A.

Application Field

The AZ1117H-2.5TRE1 is mainly used for voltage regulation of computers, communications, automotive electronics, medical and industrial control. Its low voltage dropout makes it an ideal choice for automotive applications. It is also suitable for post-rectification and power supply systems with lower current.

Working Principle

The AZ1117H-2.5TRE1 stabilizes output voltage using a resistor divider and internal current limit circuit. This device is a voltage regulator in which internal transistors act as the switching elements according to the output voltage. When the output voltage exceeds the reference voltage, the internal bipolar transistors are switched on and its current output decreases. The internal current limit circuit also protects the device from overload protection. The voltage drop in the AZ1117H-2.5TRE1 is very low, and it can output very low dropout voltage without any additional external components.

Conclusion

The AZ1117H-2.5TRE1 is a low-dropout linear voltage regulator designed for computers, communications, automotive electronics, medical, and industrial devices. It is provided with a 7-pin SOP package and provides large output current of 1A. It uses a resistor divider and internal current limit circuit to stabilize and protect itself from overload. This device is able to output very low dropout voltage without any additional external components, making it an ideal choice for post-rectification and low current power supply systems.
