An additional, uncommitted, general purpose op-amp is also included. This op-amp, capable of sourcing 20 mA
of output current, can be used for a number of auxiliary functions including the sensing and amplification of a
feedback error signal when the 2.5-V output is used as a system reference.
These parts operate over an 8-V to 40-V input supply range and require a typical stand-by current of only 7 mA.
over operating free-air temperature range (unless otherwise noted)
