It is recommended to insert bypass capacitors between input and GND pins, positioning them as close to the pins as
possible. These capacitors are 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. Use X5R or X7R ceramic capacitors, which offer good temperature and DC bias characteristics as well as
stable high voltages.

Power dissipation (Pd)
Power dissipation calculations include output power dissipation characteristics and internal IC power consumption. 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.
