AD587
Precision High Current Supply
+V
IN
For higher currents, the AD587 can easily be connected to a power
PNP or power Darlington PNP device. The circuits in Figure 15a
and 15b can deliver up to 4 A to the load. The 0.1
µF
capacitor
is required only if the load has a significant capacitive component.
If the load is purely resistive, improved high frequency supply
rejection results can be obtained by removing the capacitor.
