Tiny 3.3v low-dropout DC-DC voltage regulator module delivers up to 1A output current and has an on-board self-healing polyfuse. It is perfect for powering your breadboard projects or powering your own designs.

Based on the ZLDO1117 low-dropout positive voltage regulator with 1A output current capability, the module has a 2% tolerance across the industrial temperature range and is guaranteed to have lower than 1.2V dropout at full current load making it ideal to provide well-regulated output from supply voltage of 4.2 to 12v. It is ideally suited to provide well-regulated supplies for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply.

Combined into a tiny 3-pin module with standard VIN/GND/VOUT pin arrangement and 2.54mm-pitch header, with all supporting components (including a self-healing polyfuse) already on-board, this linear voltage regulator module is ideal for your next project. It can be used as a drop-in replacement for monolithic voltage regulator ICs, saving board real-estate and reducing component count. The header is breadboard-friendly and it includes all of the protection you will need for prototyping.
