i have connected the regulator as shown in the attached figure.the input is taken from an adaptor,the +ve terminal of the adaptor is connected to the gnd of 7905 and the -ve is connected to the input, the output is the voltage between the output pin and the gnd pin but i have an output of -1.5v although the input is 12v, is this connection right or should i use a center tapped transformer to have negative voltage.
