Hello ,I got this good QORVO manual shown below it uses a combination of regulators and a comporator.
all the component there are analog
LT1716 -analog comparator
LTC1261LCS8-4 - negative generator
LT1761-BYP- analog regulator
Could you reccomend me names of similar components which could do the same method using a microcontroller?
Thanks.

If you know what and why you are doing, the thing you are probably looking for is a Power Management Integrated Circuit. There are obviously other brands apart from NXP.

Hello eutectique,Could you please help me with a name of programmable voltage regulator i could use instead ?
Thanks.

Hello eutectique, Regarding the LTC1261LCS8 (datasheet link shown below)In order to stick with the QORVO manual can I Turn on and off the voltage regulator with a MCU using SHDN pin ?
I want to use ESP8266 which is 3.3V GPIO.
Suppose i want to turn this device on so i send GPIO pin into logical 1 which is "3.3"
However the device working when the SHDN is floating.
How do i connect the GPIO pin to the LTC1261L so i could turn it ON and OFF with GPIO pin?
Could you make some visual schematics so i'll the method of doing that? (if its possible)
Thanks.
Thanks.
