Hello I have the following question
Is possible to reduce the current consumption by changing Vref by Linear Regulator ?
http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=lmp91000&fileType=pdf
Voltage Reference input (pin 11)
Vref: http://www.ti.com/lit/ds/symlink/lm4120.pdf vref :2.5 (160 μA Typ)
Linear Regulator: http://www.ti.com/lit/ds/symlink/tps79718.pdf vout:1.8v (1.2μA typically)
The voltage is always greater than 3 volts than maintains the voltage at 1.8V in the linear regulator.
Is possible saving some current supply extending battery life ?
Thanks,
Juan
