AD587

Precision High Current Supply

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.
