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.

PRECISION CURRENT SOURCE

The design of the AD586 allows it to be easily configured as a

you can vary the load current from the quiescent current (2 mA

typically) to approximately 10 mA. The compliance voltage of

this circuit varies from about +5 V to +21 V depending upon

PRECISION HIGH CURRENT SUPPLY

For higher currents, the AD586 can easily be connected to a

power PNP or power Darlington PNP device. The circuit in

Figure 16 can deliver up to 4 amps to the load. The 0.1
