Storage temperature  Tstg  –65 to 150  °C   
Notes:    The absolute maximum ratings are values, which must not individually be exceeded, and furthermore no two 
of which may be realized at the same time. 
  1.  The input and output volta ge ratings may be exceeded if the input and output clamp-current ratings are 
observed. 
  2.  This value is limited to 5.5 V maximum. 
  3.  The maximum packa ge power dissipation was calculated using a junction temperature of 150°C.
