Introduction
As the name implies, a voltage regulator adjusts or controls the voltages of any electronic circuit. This means, that it takes any input voltage and converts that into a higher or a lower voltage according to the need of the electronic circuit. However, some voltage regulators also include some greater features. For example, they can handle greater voltage spikes, allow reverse polarity protection, and also remove unwanted noise signals. So, today in this article we will make a “Voltage Regulator Circuit 5V to 3.3V”.
To make our circuit, we are using the AMS117 voltage regulator IC. The IC consists of three pins and has a variable voltage range from 1.25V to 13.8V. But, Ic is popularly used to regulate between 3.3V to 5V. Moreover, its output current is 1000mA and the maximum drop-out voltage is 1.3V
