Voltage regulators are electronic components that provide a regulated output volate, regardless of input voltage or current changes in the supply. The AZ1117CH-1.8TRG1 linear voltage regulator is a low-dropout (LDO) type device that provides a regulated output voltage of +1.8V. It has a guaranteed max input voltage of 7V, making it suitable for applications such as RF transcievers and baseband processors.

The AZ1117CH-1.8TRG1 uses an on-chip power MOSFET, operated as a series linear regulator, to regulate the output voltage. The MOSFET operates in linear region, which requires few external components compared to switching regulators. In addition, its low dropout voltage of max 160mV typically makes it applicable to systems with low supply voltages.

The AZ1117CH-1.8TRG1 uses a simple two-pin setup to power the regulator. At the input is VIN, which is the unregulated input voltage, and the output the regulated output voltage, VOUT. This output voltage is maintained within a guaranteed ±10mV of the target value over specified temperature and load conditions. The device also has an external shutdown pin, TP, to provide power saving option. The shut down current is typically 1µA.

One of the main applications of the AZ1117CH-1.8TRG1 is RF transceivers. As a low-dropout linear regulator, it is ideal for applications such as digital TVs, external modems, and automotive infotainment systems where a regulated voltage output is required in a very low supply voltage environment. Other typical applications include voltage regulation of baseband processors, power management, and portable electronic devices with battery operation.

The AZ1117CH-1.8TRG1 is certified to AEC-Q100 standards, meaning it is suitable for automotive applications. It is available in a variety of thermal packages for most applications. The device is rated for a temperature range of -40°C to +125°C and is sold in quantities of 5,000.

The AZ1117CH-1.8TRG1 linear regulator offers excellent performance with low dropout and low output noise. Its simple 2-pin configuration, high reliability and wide temperature range make it an excellent choice for many low voltage regulation applications.
