Re: Genuine DS1210 NVRAM controllers
That's OK as long as the input supply voltage has generous headroom between the unregulated input voltage and the minimum input voltage so you could aim for a shutdown input voltage of (say) 8V if the unregulated input is normally no less than 9V on full load.
On mine, where I have the difference between input and output volts as low as possible I would have to set / choose the threshold voltage very carefully.
