Your cart is empty.The LM317 is a monolithic integrated circuit in TO-220 packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by means of a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.

These worked perfectly in power supply circuit as designed. Good value and fast shipping!

Worked great. Installed on pre-made regulator boards that came with bad regulator ic's

The old standby 3-pin adjustable voltage regulator IC. Item description is accurate. I've only used a couple of them at this time, but they are performing flawlessly. Product was well packaged for the journey here and arrived in fine condition and delivery was timely as well. I recommend this product and when I need more I'll definitely be ordering from them again.

All 15 pieces came on time, packaged in together in a little plastic ziplock bag. I've used 4/15 of these as of now for little projects and they all work great! There's so many possibilities.

I wish I could negatively review these. A true LM317T has a voltage output of 1.2V when there is no resistance. That's how these are advertised, and after buying and testing a batch, these do not meet that spec. I'm not sure that these are, but they aren't LM317T's.

I bought these to use in a couple projects where I need fixed voltage outputs. When the packaged arrived, they were 7805's instead. I immediately contacted Teenitor, which shipped me a set of replacement ICs. The replacements were indeed 317's, and the ones I used worked exactly as they should.
