Description
7Semi 5V to 3.3V 1A LDO Low Dropout Regulator Breakout with ENABLE
The 7Semi 5V to 3.3V 1A LDO Low Dropout Regulator Breakout with ENABLE is a compact power regulation module designed to provide a stable 3.3V output from a 5V input source. It features a high-efficiency low dropout (LDO) linear regulator that can supply up to 1A of current, making it suitable for powering 3.3V logic devices, sensors, and microcontrollers. The module also includes an enable pin for on/off control, allowing easy integration into automated or power-saving circuits. Its small form factor and reliability make it ideal for embedded and prototyping applications.
