Output Voltage  
Consider Figure 2. The resistance R1 generates a constant  
current flow, normally the specified load current of 10mA.  
This current will go through the resistance R2 to set the overall  
output voltage. The current IADJ is very small and constant.  
Therefore its contribution to the overall output voltage is very  
small and can generally be ignored.  
Output Voltage  
The fixed voltage LDO voltage regulator are simple to use  
regulators since the VOUT is preset to the specifications. It is  
important however, to provide the proper output capacitance  
for stability and improvement. For most operating conditions  
a capacitance of 22uF tantalum or 100uF electrolytic will  
ensure stability and prevent oscillation.  
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 R1 resistance from the resistor divider to the case,  
and not to the load. For the same reason, it is best to connect  
the resistor R2 to the Negative side of the load.
