An absolute staple! The ubiquitous L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage.

## Pricing

- **Price:** $0.92 (inc GST) — $0.84 AUD, exc GST
- **Quantity discounts:** 5+ $0.79 (exc GST) · 25+ $0.75 (exc GST) · 100+ $0.74 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 18 today; more stock is typically available with a 5–12 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE05291:1` (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/CE05291:1.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 5V. With internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.

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.

Features

- Input Voltage: 7 - 18 V
- Output Voltage Fixed: 5V
- Dropout Voltage Vdo: 2V
- Output Current: 1A
- Voltage Regulator Case Style: TO-220
- Input Voltage Max: 35V
- Input Voltage Min: 7V
- Supply Voltage Max: 20V
- Supply Voltage Min: 7.5V
