i'm doing a project with esp32 (3.3v), dht11(3v-5v), soil sensor (3.3v-5v the cheapest Chinese), nrf24l01 (2.6 - 3.6v). I'm using lifepo4 right now (3.32v) but when the battery drop about 3v, soil sensor won't work.
So I'm gonna use lipo 18650 4.2 max, then use step down LM2596 to regulate at 3.3v.
My question is, when i connect battery to 4.2v,2.6Ah --> LM2596 --> 3.3v. do I receive 2.6A at output too? I mean is it always drain 2.6A? or it just drains Operating quiescent current: 5mA.
Sorry if this is a noob question
