Nest Camera (indoor/outdoor) battery on existing wired supply

[isangaft220]

I need to know if the Nest Cam (Indoor/Outdoor) Battery model can internally regulate a supplied voltage of 9v from an existing power supply down to its internally required voltage or if I need to step it down to the 7.5v that the documentation indicates. The documentation (both the tech specs page and the support page) indicates no VCC minimum or maximum range when power supplies may be +/-5% regardless. Is this the case, that the voltage range must be within +/-5%, or does it have an internal regulator that may handle an overvoltage condition of 20% without any damage?

Hello isangaft220,

Thanks for reaching out here in the Community. Nest Cameras don't have an internal regulator and we don't recommend putting an over voltage to the Nest Cameras because it'll have a negative effect in the long run. Let us know if you have more questions in mind.

Regards,

Thank you for your response.

However, it is strange that, given my custom-built power supply, STMicroelectronics has recently discontinued the L78S75CV (as of May 11, a few weeks after I placed my Digikey order for this part), which is the only voltage regulator I can find to regulate 7.5v@2a. The only alternative is 8v, which is at +6.667%, outside the ±5% tolerance range for VCC (±5% being 7.125v-7.875v). I hope and assume the industry will supply an alternative by the November 15 last-buy date, given the common usage of 7.5v for VCC, or more complex means of regulating for 7.5v will become necessary...
