Hi all ,
I was wondering if someone would be able to help me with my circuit.
I am trying to make a low current sleeping device so I am using the MCP1700-3302E with a large 3.7v battery. I am powering the SIM7000 directly via Vbat and then powering the Arduino pro mini 3.3v via the MCP1700.
I currently have the issue that the high current draw of the sim7000e (2amps peak) knocks out my voltage regulator I am using to power my Arduino and causes a reset.
The LDO has inbuilt surge protection and I believe this is why it is restarting.
Does anyone know how I could put a circuit before the regulator to protect it from the high switch on the current of the sim7000?
