Hello,
I'm working on a system that features a BLE SoC and a Temp Sensor- TMP117. I am trying to find the lowest power and lowest cost solution. The TMP117 operates from 1.7 V to 5.5 V and typically consumes 3.5 μA. The BLE SoC is powered by a 3V coin cell. From my understanding, all of the BLE SoCs in our portfolio would be able to power the TMP117.
Initially, I had the BLE SoC controlling a load switch between the coin cell and TMP117 (left image). But, eliminating the load switch would save a lot of power and cost. Would the right solution with no load switch work?

I'd appreciate an expert's confirmation
