This circuit generates three supply voltages using a minimum of
components. Diodes D2 and D3 perform full-wave rectification,
alternately charging capacitor C2 on both halves of the ac cycle. On the
other hand, diode D1 with capacitor C1, and diode D4 with capacitor C3
each perform half-wave rectification. The full-and half-wave
rectification arrangement is satisfactory for modest supply currents
drawn from -5 and +12-V regulators IC3 and IC2.

You can use this circuit as an auxiliary supply in an up-based
instrument, for example, and avoid the less attractive alternatives of
buying a custom-wound transformer, building a more complex supply, or
using a secondary winding, say 18 Vac, and wasting power in the 5-V
regulators.
