Pololu D42V55F5.3 5.3V, 6A Step-Down Voltage Regulator
Efficiently converts up to 60V input to stable 5.3V output
Offers input reverse voltage protection and over-current protection
Features optional enable input for low-power mode
Supports power-good output for fault detection and voltage monitoring
Includes thermal shutdown and soft-start features for extra safety
The Pololu D42V55F5.3 5.3V, 6A Step-Down Voltage Regulator is engineered to efficiently convert higher input voltages, up to 60V, to a stable 5.3V output. This device is a type of switched-mode power supply, also known as a DC-to-DC converter, which is particularly effective when there is a significant difference between the input and output voltages.
The regulator is equipped with several protective features to ensure reliable operation. It includes input reverse voltage protection, which safeguards the device from damage due to incorrect input polarity. Additionally, it has over-current protection to prevent excessive current flow, and a thermal shutdown feature to protect against overheating. The soft-start feature is designed to limit inrush current, thereby reducing the risk of damage during power-up.
This regulator also offers an optional enable input for entering a low-power state, making it suitable for energy-efficient applications. The power-good output facilitates sequencing, fault detection, and voltage monitoring, enhancing its utility in complex systems.
Note: Ensure proper handling to avoid exposure to high voltages and currents that may pose safety risks.
Six connections arranged on a 0.1″ grid for compatibility with solderless breadboards, 0.1″ male headers, and 0.1″ female headers.

If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
Returns under this policy concern non-defective products. In the case of a confirmed manufacturing defect, remedies are handled under the Warranty terms, at RoboItchi's discretion. See the Warranty section.
Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
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.
On-Demand Items — Standard catalogue products not stocked by RoboItchi and ordered specifically to fulfill a customer request.
To request a return, submit a support ticket from your account under My Support Tickets to obtain a Return Authorization (RA) number. Returns without an RA number will be refused.
