... Figure 1. Simplified Schematic Device Power Dissipation Considerations The ADR380/ADR381 are capable of delivering load currents with an input voltage that ranges from 2.8 V (ADR381 only When this device is used in applications with large input voltages, care should be taken to avoid exceeding the specified maximum power dissipation or junction temperature that could result in premature device failure. The following formula should be used to calculate a device’ ...

... Many times in low power applications, the need arises for a pre- cision current source that can operate on low supply voltages. As shown in Figure 4, the ADR380/ADR381 can be configured as a precision current source. The circuit configuration illustrated is a floating current source with a grounded load. The reference’s output voltage is bootstrapped across R the output current into the load ...
