a. The XR71211 is rated over a junction temperature range T_Jof -40°C to +125°C. For a given set of operating conditions, T_Jhas to be calcu-

lated in order to make sure it does not exceed maximum specification. Use equation T_J= T_A+ (P_Dx _JA) where _JAis the package thermal

impedance, T_Ais the ambient temperature and P_Dis power dissipation. P_Dis calculated from P_D= (V_IN- V_OUT) x I_OUT

b. Dropout voltage is defined as the input to output voltage differential (V_IN- V_OUT) where the input voltage is low enough to cause the output

voltage to drop 2% from the nominal value.
