Is it possible to deliver a linear voltage regulator with the following specficiations:
- input reference voltage is from 0.8V to 1.4V
- output voltage has to follow the input reference voltage, it is the voltage connected to the load
- deliver about 1mA to the load regardless of the output voltage, that is, when the output voltage changes from 0.8V to 1.4V, the output current has to be constant at 1mA.
In my understanding, if the loading is unchanged, say fixed at 6 ohm, then increasing the output voltage will cause an increase in output current as well. So how to make the output current constant at 1mA?
