I am attempting to make a music box for my girlfriend using the [Playing WAV files with a DAC tutorial recently posted. For this project, and for many others I have in the works, I need a LDO 3.3v regulator. The problem I am having is that the best ones I can find all have the pins completely underneath themselves. While I consider myself adventurous, I am not quite ready to attempt to reflow parts onto a circuit board. Does anyone know of a good LDO 3.3v regulator that is relatively easy to hand solder?](http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=160)
ST makes the LE33CZ 3.3V LDO. It’s in a TO92 package. I often use them.
The Microchip MCP1700 also comes in a TO-92. 250 mA output.
LD1086XX33 comes in TO-220 if you want big power and a big package.
That sentence reads a lot like some of the Spam mail I get.

I am currently using this part in one of my products:

I use paste and hot air to solder it for production, but it is still very easy to solder by hand with an iron and 63/37 solder. Just tack the legs first, make sure that it is laying flat and then solder the tab.
Eagle has the library in the standard parts list.
The LM1117 is very easy to solder, as well, despite being surface-mount.
The LM1117 comes in a TO-220 package too. What current draw do you expect and what voltage are you converting from?
My current draw should be the same as the current used in this tutorial, as my entire design is based on this project. [Playing WAV Files with a DAC I am trying to use one of the 3.7v LiPo coin cell batteries that have 200mAh of current to keep the size as low as I can. If I knew how to save eagle files as jpegs, I would show you want my schematic looks like :P](http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=160)
