Other Parts Discussed in Thread: TPS737, TPS7A45
Dear Sir/ Madam,
I have some issue with LDO (TPS7A0333PDBVR) regulation to 3.3V. Could you please see circuit from attached file.
I turn off P-MOSFET by send high logic at C point and A point connect battery around 0.05V (measure before insert to HOLE3 and HOLE4) but when I try to measure at A point have voltage across around 2.1V (through the LDO out to LDO in).
So, please suggest about below circuit, how to improve for that can worked? and why have voltage leakage through the MOSFET (I turn MOSFET it off) and through LDO?
