Basic Adjustable Regulator
Output Voltage
Output Voltage
Consider Figure 2. The resistance R
1
generates a constant current flow, normally the specified load current of
10mA. This current will go through the resistance R
2
to set the overall output voltage. The current I
ADJ
is very
small and constant. Therefore its contribution to the overall output voltage is very small and can generally be
ignored
Load Regulation
Parasitic line resistance can degrade load regulation. In order not to affect the behavior of the regulator, it is best to
connect directly the R
1
resistance from the resistor divider to the case,
and not to the load. For the same reason, it is best to connect the resistor R
2
to the Negative side of the load.
