The characteristics of the IC are greatly influenced by the operating temperature. If the temperature exceeds the maximum
junction temperature T jmax , deterioration or damage may occur. Implement proper thermal designs to ensure that power
dissipation is within the permissible range in order to prevent instantaneous damage resulting from heat and maintain the
reliability of the IC for long-term operation.
The following method is used to calculate the power consumption Pc (W).
Pc = (Vcc – Vo) × Io + Vcc × Icca
Power dissipation Pd ≧ Pc
The load current Io is calculated:
Pd ? Vcc × Icca
Io ≦
Vcc ? Vo
Calculation Example:
Vcc = 6.0 V and Vo = 5.0 V at Ta = 85°C
