Hi all,
I had a circuit of output = -3V (for a lcd supply). However, when i
connect the lcd up, the voltage to that pin drops to -0.7V. Initially
I thought it may be due to the insufficient current, hence i changed
the DC convertor in the circuit to a higher power. The voltage still
drops to -0.7V.
Any reasons what caused the drop in voltage?
PS: the drop is actually increase. (-3.0 to -0.7)
Tks
