I have a 28V steady DC input, and I want to use it to charge 2x12V lead-acid batteries in series.
I want to use the LM723 IC to make an adjustable (26V to 28V) regulated output, as it has current limiting capabilities. So I used the Positive Switching Regulator figure from the datasheet with the recommended values for R1 and R2, but the circuit is not working neither in simulation nor reality.
Am I missing something? I checked multiple times.
Is my choice for the transistors right? I can't find 2N5005 and 2N5153 locally.
Can anyone help me please? Thanks.
