Added to your shopping cart. This is the basic LDV33 voltage regulator, a low drop positive regulator with a 3. Each one of these voltage regulators can output a max current of mA. This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools. Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple if any polarized components.

A basic soldering iron is all you should need. See all skill levels. If it requires power, you need to know how much, what all the pins do, and how to hook it up.

You may need to reference datasheets, schematics, and know the ins and outs of electronics. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component.

Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type.

Also, you may need a power supply that? We welcome your comments and suggestions below. However, if you are looking for solutions to technical questions please see our Technical Assistance page. Today I learn a valuable lesson. Check datasheet before soldering! And I too have now lost parts due to this pinout. Was getting really close to getting that xBee working too before I cooked it. The pinout on the one I got is correct as far as the datasheet is concerned and I had it working once.

Then rebuilt the power supply on the breadboard from my memory of the 5v one which is totally different. Another suggestion--sell these two ICs under different product numbers since they have different pin configurations. That way you'll know what you're getting. I'm a huge fan of Sparkfun, but I got burned pretty bad on this one--I ended up losing a custom PCB and most of the parts on it. Shame on me for not double checking the number on the IC but I never thought in a million years I'd get the same part with a different configuration Kinda sneaky how these got changed around.

Luckily I was only breadboarding. The tabs of both types are connected to the center pins. It was invented by Robert C. Dobkin and Robert J. Widlar in [1] while they worked at National Semiconductor.

RIP if latter. That is the excuse and a contradiction, in semi business.. I can tell you there are worse drawings, what i do,if even slightly not sure, i power it up , by self and check it. You could loose it all, its only the regulator.. So make sure you put it on a bread board and test it, before you hook it up to something else So you have one and probably tested it by now?

Or at least you know which pinout is wrong? Could you share it with us? And this is going to help your customers how, exactly??? One of the possible parts is low-dropout and the other is not.

Any way to predict which part you'll get if you order? Not sure if someone had this happen to them but when I plug in a LiPo battery charged to 4. And when trying a 9V battery to see if the reason the output was 3.

Anyone have similar issues? A dropout voltage of 1V is nothing to brag about. I've seen LDOs with dropout voltages as low as 50mV. These are usually used for converting a higher voltage power supply to what your chip needs as an input. In this case, it will take any input voltage in the range 4.

If you're talking about digital logic levels e. Can anyone confirm the pinout on this? Would this work for powering 3. Reading the datasheet I noticed the dropout voltage is 1 volt with a mA load, which is very close to what I think my circuit will draw. Because of this the minimum voltage I can use as input is 4. And the reason why I'll use a LiPo is that I need the device to be as small and thin as possible. I'm planning the layout of a project including this component on perfboard, so would this normally be standing on a finished board or should I lay it down?

You can use it either way. Just keep in mind if you're going to bend the legs to lay it flat on the board, you need to be careful not to break the legs off.

I personally adjust these for height clearance after I've soldered them into prototyping areas in my own projects. Also, keep in mind having it stand up will allow for it to get a bit more air flow-these do tend to run warm. First, check the datasheet to learn the pinout of this part.

There are several different packages in the datasheet, this one is in the TO package. You'll probably need at least one resistor between the 3. There are a bunch of good online calculators for this, such as this one for single LEDs, and this one for multiple LEDs. Have fun! I'm really new to this so I'm sorry if this is a newbish question, but do I basically just plug one pin into my 6V input, one pin into ground and the last will put out a nice 3. For many applications, this one is unnecessaraly big.

How about storing something like MCP? I ordered several of these a while back. I can confirm that the ones I received match the data sheet.

Guys: pinouts for voltage regulators are usually: 1: in; 2: GND; 3: out; and the gnd for the big back part as well. Which is the correct pinout? Those would come in handy Suggestion; sell surface mount versions of these, I have a hard time finding them in other stores.

Something like this? Just incase anyone else was confused by the doc sheet on this. Here is an easy to use constant 3. Except for a pin swap, it is as easy to use as the Need Help?
