AZ1117R-1.8TRE1 is a three rational linear voltage regulator integrated circuit, a member of the AZ1117 series of adjustable voltage regulator manufactured by Diodes Incorporated. It implements several voltage regulator functions, such as output voltage control, transition from positive to negative supply, low-voltage and over-voltage protection, and voltage source protection, in an efficient and compact package. Also included are various features, such as soft-start, current limiting and thermal overload protection.

This device is intended for use as a battery-powered voltage regulator in a variety of electronic applications, such as notebooks, cell phones, portable MP3 players and digital cameras. It is designed to provide a reliable source of voltage, prevent overcharging and thermal shut-down of the power supply, and provide a constant voltage output to the device.

The AZ1117R-1.8TRE1 integrated circuit is a compact three-terminal voltage regulator that is designed to provide a 1.8-volt regulated output. The device operates from input voltages as high as 25 volts, and offers adjustable current and voltage limiting capabilities. It has the capability to efficiently switch from positive to negative output voltage, as required. The device implements a programmable low voltage protection that makes it suitable for applications requiring battery-backed supplies.

The AZ1117R-1.8TRE1 Voltage Regulator has three main functions: to stabilize output voltage, provide current and voltage limiting, and protect against overvoltage conditions. The output voltage is adjustable using an external resistor divider, and is further regulated by internal circuitry that monitors the voltage across the device. Current and voltage limiting is provided by an internal voltage divider, and a current sense resistor, respectively. The device has the capability to detect and protect against input overvoltage conditions, by shutting off the output and providing a current limited output voltage.

The device also includes other features such as power-on-reset, soft-start, thermal overload protection, and an internal thermal shutdown circuit. The AZ1117R-1.8TRE1 voltage regulator is designed to provide a high degree of efficiency, and is optimized for portable applications. The integrated circuit is available in a thermally enhanced, 5-pin SOT-223 package, and is specified to operate over a temperature range of -40°C to +105°C.

In conclusion, the AZ1117R-1.8TRE1 integrated circuit provides an efficient and compact solution for supplying a stable 1.8-volt regulated output, with adjustable current and voltage limiting capabilities. It is designed for use in battery-powered applications, such as notebooks, cell phones, portable MP3 players and digital cameras. The device is optimized for efficiency, with features such as over-voltage protection and thermal overload protection. It is available in a thermally enhanced, 5-pin SOT-223 package, and is specified to operate over a temperature range of -40°C to +105°C.
