The AZ1117R-3.3TRE1 is a three-terminal, low dropout, low quiescent current linear regulator. This device is designed to be robust and efficient in a wide range of applications and offer superior performance over traditional linear regulators. The AZ1117R-3.3TRE1 provides a fixed output voltage of 3.3V and a wide input voltage range from 3.3V up to 28V. It is capable of supplying up to 200mA of output current with a fast transient response.

The AZ1117R-3.3TRE1 incorporates a number of features that make it well suited for applications where low dropout performance and low quiescent current are critical. The device has an internal P-channel MOSFET for power switching and a low-side current limit for protection. It also includes an undershoot protection circuit and a TTL-logic-compatible enable pin.

In order to better understand the capabilities of the AZ1117R-3.3TRE1 it is important to understand the working principle behind its operation. When the enable pin is pulled high, the internal P-channel MOSFET is turned on, allowing the device to draw current from the input voltage source. This current is then regulated and passes through the low-side current sensing resistor to the load. As the load current increases, the voltage drop across the current sensing resistor increases, causing the regulator to reduce the output voltage to maintain a constant output. The AZ1117R-3.3TRE1 also has an adjustable over-current protection circuit which will turn off the output if the load current exceeds the set limit.

The AZ1117R-3.3TRE1 is well suited for applications that require a low-dropout linear regulator with a wide input voltage range and low quiescent current. It is especially well suited for automotive, battery-powered, and low-voltage applications where power efficiency is important. The device can also be used in a wide range of lighting control, medical, industrial, and consumer applications.

In summary, the AZ1117R-3.3TRE1 is a low-dropout, low quiescent current linear regulator with a wide input voltage range and fast transient response. It is ideal for applications that require efficient, low-voltage, and low-dropout operation. This device provides superior performance over traditional linear regulators and is well suited for automotive, battery-powered, and consumer applications.
