Printed circuit board layout considerations
LM4040s in the SOT23 package have the die attached to pin 1, which results in an electrical contact between pin 2 and pin
3. Therefore, pin 1 of the SOT-23 package must be left floating or connected to pin 2.
LM4040s in the SC70-5 package have the die attached to pin 2, which results in an electrical contact between pin 2 and pin
1. Therefore, pin 2 must be left floating or connected to pin1.
