AS2815

Basic Adjustable Regulator

Output Voltage

current flow, normally the specified load current of 10mA.

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

and not to the load. For the same reason, it is best to connect

Output Voltage

The fixed voltage LDO voltage regulators are simple to use

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.
