AZ1117ID-ADJTRG1

Introduction

AZ1117ID is a linear voltage regulator designed to provide a stable low voltage power supply for load circuits and it is classified as a PMIC - Voltage Regulators - Linear. It is widely used in on-off driving, control and prevention of overvoltage, overloading and various adjustment, regulation, compensation and display circuits. The regulator offers tight load, line regulation and low dropout voltage performance, allowing it to provide up to 800mA of output current.

Application Field

The AZ1117ID is widely employed for voltage-regulated electronic equipment. These include desktop computers, notebooks, and digital information appliances. Advantages include high accuracy output voltage, low dropout voltage and good line regulation performance.

Working Principle

The AZ1117ID is based on the adjustable low dropout voltage regulator, also known as LDOs (Low Dropout Voltage regulator). It is designed by integrating a voltage reference and an error amplifier both of which provide precise control of the output voltage.

The output of the error amplifier is connected to a power transistor which acts as a variable resistor. When the voltage drops, the error amplifier reduces the resistance of the transistor, increasing the voltage until it returns to the desired level. In addition, it compensates for changes in output current and maintains the output voltage accuracy.
