Features reverse-voltage and over-current protection
Reduces quiescent current with ENABLE pin
Includes mounting holes for secure installation
Compact design with flexible connection options
The Pololu 5V Step-up Voltage Regulator U3V50F5 is a robust boost regulator designed to efficiently convert input voltages as low as 2.9 V to a stable 5 V output. This device is a type of switching regulator, also known as a switched-mode power supply or DC-to-DC converter, and it boasts a typical efficiency range of 80% to 95%. The regulator can handle input currents up to 5 A, making it suitable for applications requiring significant power conversion.
This regulator 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 2.5 V. The ENABLE pin allows the device to enter a low-power state, reducing quiescent current to approximately 20 µA per volt on VIN. The board is compact, with dimensions of 1.9″ × 0.6″ × 0.41″, and includes two mounting holes for secure installation.
Electrical connections can be made through smaller holes compatible with 0.1″ header pins or larger holes for terminal blocks, providing flexibility in prototyping and installation. The board's design includes a thick PCB, which may affect the protrusion of terminal block and header pins compared to standard PCBs. The regulator is enabled by default, and the ENABLE pin can be driven low to reduce power consumption.
Note: During normal operation, this product can become hot enough to cause burns. Handle with care.

The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RoboItchi's troubleshooting process or of a verified shipping error by RoboItchi.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A ¥10,000 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RoboItchi's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
