Polarity converter

Posted on Oct 10, 2012

The capacitor-diode output circuit is used here as a polarity converter to generate a - 5 volt supply from +15 volts. This circuit is useful for an output current of up to 20 mA with no additional boost transistors required. Since the output transistors are current limited, no additional protection is necessary

Also, the lack of an inductor allows the circuit to be stabilized with only the output capacitor.
