DUAL__52_V_AND___15_V

Output voltages are equal to preset values of regulator ICs in basic arrangement shown. R1 and D1 ensure startup of LM109 when common load exists across sup-plies. D1 should be germanium or Schottky hav-ing forward voltage drop of 0.4V or less at 50 mA. D2 and D3 protect against polarity reversal of output during overloads.-C. T.
