Applies to UA78L15C and UA78L15AC.

(2)

Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. For legacy

chip, temperature range for the UA78L15C, UA78L15AC is TJ = 0°C to 125°C. For new chip, temperature range for the UA78L15C and

UA78L15AC is TJ = –40°C to 125°C.
