increase output current in a circuit
i cannot use parallel configuration as ic is costly
second ,
i wonder how can i pull up i am getting the negative voltage from the ic , using POSITIVE voltage
ADM660 solution is good , i have to just check if this IC is availble in local market or not
to use the lm337 ,
i have a question that in the case of using lm337 from where the ic get the input current
from negative Vin ,
am i right ?
but my problem is not to regulate the out put voltage
my problem is to generate the negative out put voltage
from the positve
had i already -12 v i would not have problem
i could have used it as well
i am now trying to use
lt1074
for the negative converter
but i am unable to figure out from its data sheet that how can i control out put voltage ?
it gives the circuit of the -5 voltage but i want to have -7
if i can create -12 v then i can use some other regulator to decrease it to regulated voltage
but i believe some how we can generate the -7 regulated voltage from lt1074
please
see the data sheet and if some one can figure out which parameter control the out put voltage then let me know it
