Hi everybody
I designed this bipolar power supply that can supply +5 and -5 volts to the circuit. The positive pole gives +5v correctly, and there is no problem when connecting the load, but when the load is connected to the negative pole of the circuit, we face a voltage drop. Although I expected the negative pole to be able to conduct current up to about 200 mA, but with 30 mA, the voltage dropped from -5v to -3.8v.
This circuit is composed of 3 circuits (according to datasheets).
Vbattery = 7.4v (2 cell lipo)
How knows what is wrong?
Thank you for your answers.
