better u use a step-down/buck DC-DC convetor which will give u a nice
1.5v from a 9V battery.

U might be doing this to have longer life of battery.

if u r using 9V - 1.5V linear voltage regulator you will waste a large
amout of power.

So go for switching regulator.
they price less then 1$.

got a source for these?
