“Normally I get mine from up cycling old technology like cassette players & the like. But thought these will come in handy when I have run out of them.”
“These are considerably better than the pack of 3.3V regulators I got from aliexpress, in two important ways: they regulate voltage to 3.3V (+/-1%), and they don't set themselves on fire when connected to a 5V battery.”
“It is a nice little product page with a good overview of the different voltages of the regulators. And nice with the information and links. However the pinout for the 3.3V version COM0210 is wrong I believe.
I could not make the 3.3V version work until I read the article "Introducing Voltage Regulators" references on "Voltage Regulator" page. The correct pinout is:
3.3V pinout:
1: GND
2: Output Voltage
3: Input Voltage”
