Description The AP7365/35(LDO) evaluation modules (EVM) provide a means for the user to evaluate quickly the functionality and electrical performance of the AP7365/35 device. All inputs and outputs are brought out to test points for control and monitoring. All passive components are included on the EVM for device operation. The input pin should be connected to an external supply; the output should be connected to a load. 2.
