I'm prototyping an ultra low power wireless sensor. To consume less I run an Arduino Mini Pro at 1.8V at 8MHz with sleep 99% of time. The power comes from a LIR2032 coin cell and the 1.8V is generated from a LDO regulator HT7318. I use the regulator because my NRF24L01 will not support such as 4V voltage and cause an atmega328p consumes less with a lower voltage. I want the consumption to be as l
