Description

A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage.

This is the basic LD33CV, LD1117V33 voltage regulator, a low drop positive regulator with a 3.3V fixed output voltage. This fixed regulator provides a great amount of stability and protection for your project and with its on ship trimming this regulator is able to reach an output voltage tolerance within ±1%. Each one of these voltage regulators can output a max current of 800mA. High efficiency is assured by NPN pass transistor. In fact in this case, unlike than PNP one, the Quiescent Current flows mostly into the load. Only a very common 10μF minimum capacitor is needed for stability.
