Negative switching regulator (15 volts) using an ECG915 or ECG915D IC. For a ±5% fixed output R1 is 3.65 ohms and R2 is 11.5 ohms. in metal can applications where Vz is required, connect a 6.2-volt zener in series with the regulated output.L1 is forty turns of AWG #20 enameled copper wire wound on Ferroxcube P36/22-387 pot core or equivalent with 0.009-inch air gap (courtesy GTE Sylvania Incorporated).
