erwise specified)

Note: Testing of all parameter is performed at 25

°C. Characterisation, as well as the design rule used al-

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

°Cto 70°C) use L3234. If operations are required in the ex-

tended temperature range (-40

°Cto 85°C), use the L3234T.
