- Fri Jan 20, 2017 6:01 am #61256 Just hooked up a board with a TLV1117lv sot-223 LDO, only to realise that that the board seems to have switched the input and out pins of the LDO.

Are they LDO's that have the input on pin 2?

- Fri Jan 20, 2017 8:18 am #61264 The footprint on the board is for SOT-89, not SOT-223.
Most LDOs in SOT-89 seem to have a compatible pinout, you should double check before ordering though (XC6203 should work for example).

A 3v3 regulator can be mounted here, and the 0k middle resistor must then be removed.
