I plan on using this 3.3v regulator
It has 4 pins on the SOT-223 package
I plan on doing the following ( but want to check )
- Pin 1 - Gnd
- Pin 2 - Vout - 3.3v -- Tied to pin 4 feeding my circuit
- Pin 3 - Vin - 5v Supply
- Pin 4 - Vout - 3.3v -- Tied to pin 2 feeding my circuit
Does this look correct?
The reason I act is that pin 4 is a bit 'odd'. This question has set me straight : LDO - SOT223 - What's the Fourth pin for?
Basically its a tab for heatsinking, but it is typically connected to Pin 2.
Can I therefore safely just have a pad for the Tab(pin 4) with nothing connected to it? And use pin 2 for the vOUT alone?
