About this product
A low-dropout (LDO) linear regulator module built around the AMS1117-3.3 chip. It accepts a 4.5V to 15V input and provides a regulated 3.3V output rated up to 800mA, suitable for 3.3V logic, sensors and small microcontroller boards. A red LED shows that power is on, and the 3-pin layout fits a breadboard.

Frequently asked questions
What is the price of AMS1117-3.3 LDO 800mA 3.3V Step-Down Power Supply Module in Egypt?
AMS1117-3.3 LDO 800mA 3.3V Step-Down Power Supply Module currently costs 20 EGP in Egypt.
Where can I buy AMS1117-3.3 LDO 800mA 3.3V Step-Down Power Supply Module in Egypt?
AMS1117-3.3 LDO 800mA 3.3V Step-Down Power Supply Module is available from Microohm and Ekostra. Compare the offers above to find the best price.
What input voltage can I connect to this module?
The input range is 4.5V to 15V, so a 5V supply is a common choice. Because it is a linear regulator, the voltage difference between input and output is dissipated as heat, so a higher input voltage means more heat.
Can I use it to power an ESP32 or other 3.3V boards?
Yes, for loads that stay within 800mA. Wi-Fi transmissions on ESP32 boards cause short current spikes above their average draw, so add a capacitor close to the load and check that the module keeps 3.3V under peak current.
