Note:
Testing of all parameters is performed at 25
°
C. Characterization, as well as the design rules used
allow correlation of tested performance with actual performance 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 temperaturerange (-40
°
C to 85
°
C), use theL3234T.
