What size LED are you using? I can't get a 5MM LED in there and the hole is waaaaaayyyyy to big for a 3mm.

Hi
I've been using the LM2596 regulators modules for years with no issues. The chip is rated at 3A, far more than the Pi needs, the regulation and noise is low, low enough not to be an issue with the Pi.
I even have a Raspberry Pi web server using one of these modules that has been in continues use now since 2013, runs cool and stable. Also I've used these modules to power network cameras made using Raspberry Pi B's and home made power over Ethernet.
The only issues I have with these modules is that they are shipped with the output turned up hi, they do need to be set to 5V BEFORE connecting the raspberry Pi. The only other thing is that they don't have reverse polarity protection, that's easy to solve with either a 1 or 3A diode or a bridge rectifier.

A typical board found on Ebay http://www.ebay.com/itm/LM2596-DC-DC-buck-adjustable-step-down-Power-Supply-Converter-module-RF-/172357861111?hash=item2821543ef7:g:vPsAAOSwmLlX7Meo

I hope this was helpful
Cheers

I sure like the idea of a built in regulator like that.I've seen a lot of them aren't terribly regulated and I'd hate to blow up an expensive Pi Zero. Can you recommend one?
