AZ1117BH-2.5TRE1 is a linear voltage regulator that belongs to the PMIC - Voltage Regulators - Linear product family. It offers a wide input voltage range – 2.5V to 15V and output voltage range – 2V to 3.3V. It also provides circuit protection features such as reverse current protection, current limit protection, and thermal shut down. EMS protection is also provided in order to enjoy longer life expectancy.

AZ1117BH-2.5TRE1 is a single adjustable low dropout (LDO) linear voltage regulator, designed to provide a simple, cost effective solution for powering a wide range of mobile devices. It utilizes bipolar transistors in both converter stages and is capable of providing moderate current up to 1.5A. Its wide input voltage range and output voltage range make it suitable for use in a variety of applications such as mobile phones, PDAs, laptops, memory modules, automotive infotainment systems, Mp3 players and digital cameras.

The AZ1117BH-2.5TRE1 is a step-down regulator, which operates from input voltages of 2.5V to 15V and regulates the output of 2V to 3.3V with a maximum current of up to 1.5A. The linear voltage regulator is comprised of a series of pass transistors and a voltage reference. The voltage reference is used to set the output voltage of the regulator. This can be done manually or automatically via an external feedback circuit. The output voltage is achieved by adjusting the binary weights of the transistors, so that the proper current flows through the regulator. The output is then regulated to the predetermined voltage.

AZ1117BH-2.5TRE1 is well-suited for negative to positive voltage conversion, since it regulates the output of negative voltages, making it able to be used in high-side applications such as power supply polarity protection, negative to positive voltage conversion, and ground isolation. Additionally, the current limiting protection and thermal shut down feature both help to improve the product reliability while saving cost. As an example, if the output voltage current exceeds the current limiting protection threshold, the device will safely shut down in order to protect the load from the over current issue.

Thus, AZ1117BH-2.5TRE1 is a general purpose, low cost, compact size, and low consumption voltage regulator for powering a wide range of mobile devices. It offers adjustable output voltage, high input/output compliance, excellent transient response, low quiescent current and high power efficiency. Its reverse current protection and current limit protection offer exceptional reliability and increase its suitability for automotive infotainment and other mission critical applications. Furthermore, its wide input voltage range and output voltage range make it a perfect, low cost, solution for powering a variety of mobile device designs, while its thermal shutdown improves product reliability and saves cost.
