I have Esp01s. I want to get a constant voltage between 3.0 and 3.6 with 3 alkaline batteries. The voltage of 1 alkaline battery is 1.5 volts. What is your suggestion?
Over time, the battery's
Over time, the battery's voltage decreases. If the voltage drops below 3.3, for example 1.7v. What should I do?
Use buck boost
1.7-4.5V Input to 3.3V output buck-boost switching regulator with more than 85% efficiency.

PermalinkIn series 3 LDO will produce 3x1.5V = 4.5V.
Use an LDO of 3.3V.
