We consider a power supply as the basic electronic circuit. Because the use of power supply is everywhere in the electronics industry. It has a wide range of applications and hence there are different regulators that designers have made. It includes regulated, unregulated, constant voltage, constant current power supplies. Hence, the board modules are also there in the electronics market that works for the same purpose.

What are Voltage Regulators

Voltage regulators are the circuits that automatically regulate or adjust the voltage level. They step down the supplied input voltage to the required or desired output level and maintain that same level during the supply. Hence, makes sure that even when a load is applied the voltage doesn’t drop. There are two major reasons to use voltage regulators. First, to adjust the output voltage of the circuit. And, to keep the output voltage constant at the needed value even if the variation occurs in the supply voltage.

An Overview of AMS1117 Module

The AMS1117 series of flexible, adjustable, and fixed power supply regulators are easy to use and are guaranteed against short circuits. It includes thermal protection circuitry which shut-down the circuit if the temperature get exceeds. The module has a pin-compatible three-terminal integrated circuit. Hence, it is great for the devices having lower dropout voltage, precise tolerance, and improved stability with temperature.
