This integrated AVR has three adjustable ports with the lowest base voltage of 1.25 V which have perfect performance on keeping a steady output voltage. Besides, adjustable port has a super small current which is only about 50μA and super steady with a difference of 0.5 μA. Therefore, it can be used to form constant current and high frequency circuit. Its output current is Id plus 1.25/R1. Id is small so Io can be regarded as about 1.25/R1.
