AMS1117-3.3 LDO 800MA DC 5V to 3.3V Step-Down Power Supply Module

AMS1117-3.3 LDO 800MA DC 5V to 3.3V Step-Down Power Supply Module

The AMS1117-3.3 power supply module is a compact low dropout (LDO) linear regulator designed to step down a 5V DC input to a stable 3.3V output. Based on the popular AMS1117-3.3 regulator IC, this module provides up to 800mA output current (with proper heat dissipation) and is ideal for powering 3.3V logic devices, microcontrollers, and sensors.
