(1) Applies to UA78L15C and UA78L15AC.

(2) Pulse-testing techniques maintain T_J as close to T_A as possible. Thermal effects must be taken into account separately. For legacy chip, temperature range for the UA78L15C, UA78L15AC is T_J = 0°C to 125°C. For new chip, temperature range for the UA78L15C and UA78L15AC is T_J = –40°C to 125°C.
