| Technical Reference Note Doc #1981 TRN-AA25N-048L-050S Electrical characteristics are guaranteed over the ambient temperature range (-40 to 60C), for the full range of input voltage (VI), and for the full load range (I0 min to I 0 rated) unless otherwise noted. VI , Vo and I0 are actual operating conditions, Io rated is nominal rating.
