# Voltage Regulator - Adjustable

**Type:** Product page · **SKU:** COM-00527 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/voltage-regulator-adjustable.html ([markdown](https://core-electronics.com.au/voltage-regulator-adjustable.html.md))

This is the LM317TG voltage regulator, a three-terminal positive regulator with a 1.2V to 37V adjustable output voltage. This adjustable regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Did we mention that this guy is easy to use? It only requires two external resistors to set the output voltage. Each one of these voltage regulators can output a max current of 1.5A.

## Pricing

- **Price:** $3.80 (inc GST) — $3.45 AUD, exc GST
- **Quantity discounts:** 5+ $3.35 (exc GST) · 25+ $3.28 (exc GST) · 100+ $3.15 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 300 more in 5–11 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=COM-00527:1` (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/COM-00527:1.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)
