## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09951:1` (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/CE09951:1.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

Use this regulator to provide a reliable 3.3V for your projects. This genuine STMicroelectronics LDO is capable of providing up to 800mA which ought to be enough for most maker projects that operate at 3.3V.

If you're prototyping with this part, we have the perfect [SMT protoboard](https://core-electronics.com.au/makerverse-smt-protoboard.html) to help you get started.

Linear voltage regulators burn off excess power as **heat**, which means the device will get hotter for:

- higher currents
- greater differences between input and output voltage.
 
This product will be supplied as cut-tape or loose individual units.

**Features**

- Input Voltage: 4.5 - 15 (abs. max) V
- Output Voltage Fixed: 3.3V
- Dropout Voltage Vdo: 1.2V max
- Output Current: 800mA
- Package: SOT-223
