Pololu 9V, 300mA Step-Down Voltage Regulator D24V3F9
Converts up to 42V to stable 9V output
Boasts 80%-90% efficiency
Includes short-circuit protection
Features over-temperature shutoff
Compact design: 13mm x 10mm x 3mm
The Pololu 9V, 300mA Step-Down Voltage Regulator D24V3F9 efficiently converts higher input voltages up to 42 V to a stable 9 V output. This switching regulator, also known as a DC-to-DC converter, offers an efficiency range of 80% to 90%, making it superior to linear regulators, particularly when there is a significant difference between input and output voltages.
The regulator features short-circuit protection and thermal shutdown to prevent overheating. It operates at a 1.25 MHz switching frequency and has a typical no-load quiescent current of 2 mA. The device lacks reverse-voltage protection.

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.
