USB Reg Board
The USB Reg Board is a smart accessory board, which lets the users to power their electronic devices by connecting them to the USB port of their personal computer. This plug-and-play additional board just needs to be plugged in to a USB hub so that the device can get powered over the USB connection. The USB regulator board has been designed to provide both 3.3V and 5V DC outputs. While 5V output comes directly from the USB, an incorporated MC33269DT power regulator circuit enables the board to produce 3.3V reference also. So, what this compact sized board actually does is that it allows you to conveniently power any of your 3.3V or 5V prototype device directly from USB port of your PC in a very simple and cost-efficient manner.
This USB Reg additional board comes equipped with three solder pads that enable it to get connected to 3.3V, 5V and GND outputs. After getting a header soldered in to the regulator board, this board becomes compatible for use with breadboards too.

MC33269DT Power Regulator Circuit
The MC33269DT is an 800 mA, adjustable output, low dropout voltage regulator. This fixed and adjustable, positive voltage regulator features a 1.0 V dropout composite PNPâˆ’NPN pass transistor, current limiting, and thermal shutdown. It comes particularly designed for being put to use in applications that need low input voltage.
The USB Reg Board operates on standard USB 5V power supply.
The small size of the USB Reg Board helps in easy integration of the board in your prototype as well as in your final product. Ideal for use in low input voltage applications, this device helps the circuit designer to ensure precision voltage.
Regulation in order to minimize the power bills and losses too.
