Hello
I've got some issue with correct work of lm2776.
If I use 1uf capacitor that is connecting between C+ and C- the Vout is -4.6V (Vin is 4.9V).
But when I connect 2.2uf capacitors to Vin and to Vout - everything is going wrong. The Vout becomes -0.5V, and after removing those 2 capacitors the situation do not back to initial level.
It seems that the lm2776 has stop worked after connecting two 2.2uf capacitors.
How critically the using of 2.2uf capacitors of TDK is?
And I found mismatch between capacitance of capacitors in and in
So which exactly those capacitors should be? What manufacture and what capacitance?
Thank you very much if you save our time.
