Christmas Opening Times

If you need a UK delivery by Christmas day, you are advised to order Special Delivery on the 21st or the 22nd of December, as Royal Mail have suspended their delivery guarantee for orders dispatched on the 23rd. Hobbytronics will not be open from the 24th to the 28th of December. You can still place orders, but they will be not be processed and customer support will not be provided during this time.  In addition, there is an early mail collection on the 31st of December and another UK Bank Holiday on the 1st January. We at Hobbytronics wish you a very happy holiday period, and a happy new year.

Covid-19 - IMPORTANT UPDATE

We are still seeing some delays to the Royal Mail and Airmail delivery services with some orders taking much longer than expected to be delivered. If your order is taking longer than usual to arrive, please be patient and bear with us. If you have an urgent requirement, for UK we recommend choosing the Special Delivery option: although next day delivery is not currently guaranteed, your package will still get priority handling and will usually arrive within 1-2 days. For international orders, we suggest choosing the airmail express option at a minimum if you need the goods in a timely manner, and to consider using our courier service (UPS, FedEx or DHL) if it is truly urgent. This is especially relevant if you are ordering outside of Europe.

If you order a custom stencil or custom laser cutting, please make sure to follow the instructions on the product page as closely as possible to avoid additional delays.

We apologise for any frustration this may cause. Stay safe.

4.5-20V Fine-Adjust Step-Up Voltage Regulator U3V70A This powerful synchronous switching boost regulator efficiently generates a finely adjustable output voltage between 4.5 V to 20 V from an input voltage as low as 2.9 V while using an input current as high as 8 A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load.
