Is there a recommended solution for reverse polarity protection, i.e. if the power source (battery pack) is connected the wrong way to the Vin and GND pins of the LP2985 voltage regulator?
I am using the variant with Vout = 3.3V. The battery packs can be up to 9V, but they are connected to Vin and GND via wires. So it is easy to connect them the wrong way.
My goal is to:
- Protect the voltage regulator from damage.
- Protect the device connected to Vout from voltage > 3.3V.
