## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA184:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA184:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This kit is for making your own breadboard-friendly very low dropout adjustable power supply. A good power supply is essential to electronic projects. While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs

- MIC2941 regulator has guaranteed 1.25A output
- Low dropout, only 40mV - 400mV compared to 1.25V - 2.0V for LM317. This means you can use a wider range of output voltages including generating 3.3V from as low as 3.7V (such as 3 AA's or a lithium ion battery)!
- Short circuit and overheating protection
- Input diode to protect circuitry from negative voltages or AC power supplies.
- 2.1mm DC jack and terminal connector for voltage inputs
- Two indicator LEDs for high and low voltages
- Output selection switch to select from **3.3v,**  **5v** and **Adjustable** (also has a breakout for the voltage you're powering the boad with)
- Onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage. (20V max)
- On/Off switch for entire board
- Heat sink included

Project kit comes as components to be soldered to the included PCB. It's not a difficult project, about 30-45 minutes with a soldering iron. Even beginners can make it! You'll need a soldering iron, solder, diagonal cutters and a PCB holder such as a helping hand tool. Breadboard and battery clip or DC power supply is not included, you can use any DC power supply with 2.1mm plug (we have a nice one in the shop).For design documents, instructions, parts list, etc. Check out the project webpage!
