Greetings!
Do you know what a switching regulator with associated components costs?
Hands up everyone who would pay $100 for the BS2px(x for eXtreme [noparse]:)[/noparse]
An alternative would be to use an external, regulated PSU...

TO-220 linear regulator!!!!!!!! Thats 1/3 the size of a stamp
alone!!!
Step into the realm of switching regulators. A SOT23-5 switching
regulator switching at 1.4 Mhz with an output current of 400 mA at 5V
and a max input voltage of 12 V can be 90% efficient and take up less
board space that the body of your TO-220. Think small. Who needs a
heatsink??? With an 8 pin SOIC switching regulator outputs of up to 5
A are common.
Take a look at the Javelin stamp. It uses a switching regulator.
