Hello,

Somebody can suggest an inverter to obtain -5v (100mA) from +10v .

Thks!
 

Take a look at the following for the MAX739 :

for a low power converter use the 555 timer to generate a 50 - 100 KHz square wave to drive a two diode rectifier (diodes are reversed from a regular two diode rectifier to generate a negative voltage). You should have -10 V coming out of which you can use 7905 regulator to obtain -5 V.
