ADM8839
It is possible to configure the ADM8839 to supply up to 400 μA
on the ±15 V outputs by changing its configuration slightly, as
C5, 2.2μF
The configuration in Figure 17 can supply up to 400 μA of
current on both the +15 V and the ?15 V outputs. If the load on
the ±15 V does not draw any current, the voltage on the ±15 V
outputs can rise up to ±16.5 V (see Figure 18). In this
configuration, VOUT (Pin 2) is connected to +5VIN (Pin 5).
