Power dissipation (Pd)
1. Power dissipation (Pd)
Power dissipation calculations include estimates of power dissipation characteristics and internal IC power consumption,
and should be treated as guidelines. In the event that the IC is used in an environment where this power dissipation is
exceeded, the attendant rise in the junction temperature will trigger the thermal shutdown circuit, reducing the current
capacity and otherwise degrading the IC's design performance. Allow for sufficient margins so that this power dissipation is
not exceeded during IC operation.

2. Power dissipation/power dissipation reduction (Pd)

*Circuit design should allow a sufficient margin for the temperature range so that PMAX < Pd.

Input Output capacitors
It is recommended to insert bypass capacitors between input and GND pins, positioning them as close to the pins as
possible. These capacitors will be used when the power supply impedance increases or when long wiring paths are used, so
they should be checked once the IC has been mounted.
Ceramic capacitors generally have temperature and DC bias characteristics. When selecting ceramic capacitors, use X5R or
X7R, or better models that offer good temperature and DC bias characteristics and high tolerant voltages.
