## Overview

The AMS1117-3.3V is a low dropout linear voltage regulator delivering a stable 3.3V output at up to 1A current. Featuring a maximum dropout voltage of 1.3V and precise on-chip voltage trimming, it ensures reliable performance for laptops, mobile phones, and battery chargers. Its compact SOT-223 surface-mount package makes it ideal for space-conscious electronic designs, while built-in current limiting protects both the regulator and connected devices from overload damage.

## Description

The AMS1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The AMS1117 devices are pin compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount SOT-223 package. Package include: 10pcs *AMS1117-3.3V

Review: MAKE SURE you use the correct pin configuration. - My jet ski original display quit working. I ordered this tachometer from desertcart. The tachometer is on top. It uses a large 3volt button battery. I need to be able to use power from the jet ski. This regulator worked perfect. Tests at 3.25 volts with backlight off, and 3.23 volts with backlight on. Regulator stayed cool even with the backlight on.
Review: Replacement part - I used one of these to replace a regulator on an ESP32 development module. So far, there have been no problems and the output is maintained at 3.3V.

## Features
