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?
In reply to Use LDO Regulator by Sourav Gupta
Over time, the battery's voltage decreases. If the voltage drops below 3.3, for example 1.7v. What should I do?
1.7-4.5V Input to 3.3V output buck-boost switching regulator with more than 85% efficiency.

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