Copper pour added on the top and bottom layer for ground net and all passive components with thermal relief. Input connector – text “Input 5V” “Ground” and “Enable”, Output connector – text “Output - 3.3V” “Ground”. PCB board with the text (“DC-DC Power Supply – Rev1”). Add 4 mounting holes (3mm) on all corners with 2 fiducials diagonally opposite. Assemble and route the components as recommended by the datasheet. Identifying the key points to consider for PCB design datasheet. Molex 3 pin 2.54mm connector on the input and 2 pin connector on the output. Following the block diagram provided for creating the schematic and using the datasheet for creating the footprint and symbol. 
PCB clearance to be set as 0.2mm and track width to be 0.3mm for power line and 0.2mm for rest of the circuit. Defining a PCB board size of 40mm x 40mm for a 2 layer PCB. To design a PCB using Altium ECAD software for a low dropout voltage regulator (LDO) for 5V input, stepping down to 3.3V
