I've got a voltage regulator in a circuit, along with its recommended protection diode:
On my PCB, I'm using large copper pours for the Vin (Pin 1) and Vout (Pin 3) connections, as these are used frequently in other high current components in the rest of the circuit.
My top copper pours are split exactly in half, with the Vin pour to the left of the chip (red) and the Vout pour to the right of the chip (blue). I have a seamless Ground plane on the bottom layer.
Can I simply place the protection diode near the chip - with its terminals connected to the Vin and Vout planes as below? Or should I be routing traces specifically to isolate the diode/chip from the pours (forcing the diode to be the "gateway" to the pours for the chip?)
