Pololu 12V Step-up Voltage Regulator U3V50F12
Converts low voltage to stable 12V output
Features reverse-voltage protection
Operates with 80%-95% efficiency
Compact design with versatile connections
Includes thermal and over-current protection
The Pololu 12V Step-up Voltage Regulator U3V50F12 is a robust boost regulator designed to efficiently convert a low input voltage to a stable 12V output. It operates with input voltages starting from 2.9V and can handle input currents up to 5A. This regulator is part of a family of switching regulators, also known as switched-mode power supplies or DC-to-DC converters, which are renowned for their high efficiency, typically ranging from 80% to 95%.
This device features integrated protections, including reverse-voltage protection, over-current protection, thermal shutdown, and an under-voltage lockout that activates when the input voltage falls below 2.5V. The regulator is equipped with an ENABLE pin, allowing it to enter a low-power state, significantly reducing quiescent current draw. The board's compact design includes two mounting holes for secure installation and offers multiple connection options, such as soldering wires directly or using terminal blocks and header pins.
The regulator's efficiency is a critical performance metric, especially in applications where battery life or heat dissipation is a concern. The efficiency varies with different combinations of input and output voltages and loads. The board's design accommodates various prototyping arrangements, with labeled connections and compatibility with solderless breadboards.
Note: During normal operation, this product can become hot enough to cause burns. Handle with care.

The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
