The tolerance envelope is the maximum output voltage variation due to changes in output loading. RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260C for 10 seconds. The pin termination nish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. They are backward compatible with Sn/Pb soldering systems.
