I have a IR Receiver with input(5V max) ground and output, what i dont understand is, im using a 5V regulator for the input of the IR receiver and if i use a brand new 9V battery, the output remains high no matter what, but if i use a old 9V battery of the same brand that has lost about 1.5 - 2V the output works fine(goes low when it receives a signal from a IR remote)
Does anyone know why this is happening? i tested the voltage on the regulator with a mutimeter with both batteries, and they both show 5V?
