low correlation of tested performance with actual performances at other temperatures. All pa-
rameters listed here are met in the range 0 C to +70 C. For applications requiring operations in
the standard temperature range (0 C to 70 C) use L3234. If operations are required in the ex-
tended temperature range (-40 C to 85 C), use the L3234T.
