Dear Expert,
To do a dual design between AMC1304L25 and AMC1305L25, Can AMC1304L25 LDOIN left floating and VCAP connect to external 5V or 3.3V power supply?
Thank you,
Dylan
Hi Dylan,
To implement a dual design with the AMC1304L25 and AMC1305L25, we do not recommend leaving pin 6 (LDOIN) floating. We recommend using both LDOIN and VCAP capacitor footprints and then a zero ohm resistor to divert the supply to pin 6 or pin 7 as needed.
