This circuit uses a LT1110 DC-DC converter (switcher) to form a 1.5vdc to +5vdc and -5vdc power supply. The LT1110 has an internal 70kHz oscillator which allows use of surface mount inductors and capacitors. Quiescent current is 300 microamps. This circuit delivers about 4mA for each output. L1 is a Coilcraft 1812LS-823.
