About power dissipation (Pd)
As for power dissipation, an approximate estimate of the heat reduction characteristics and internal power consumption of
IC are shown, so please use these for reference. Since power dissipation changes substantially depending on the
implementation conditions (board size, board thickness, metal wiring rate, number of layers and through holes, etc.), it is
recommended to measure Pd on a set board. Exceeding the power dissipation of IC may lead to deterioration of the original
IC performance, such as causing operation of the thermal shutdown circuit or reduction in current capability. Therefore, be
sure to prepare sufficient margin within power dissipation for usage.
Calculation of the maximum internal power consumption of IC (PMAX)
PMAX=(VIN-VOUT)×IOUT(MAX.) (VIN: Input voltage VOUT: Output voltage IOUT(MAX): Maximum output current)
