: 0.1 to 0.47 ÂµF. Be sure to connect to prevent abnormal oscillation. For using capacitors, film capacitors

whose voltage and temperature characteristics are excellent are recommended. Take care that some

monolithic ceramic capacitor is inferior in the temperature and voltage characteristics. When using the

monolithic ceramic capacitor, the CIN needs to be held these capacities in voltage and temperature used.

: 10 ÂµF or higher. Be sure to connect to prevent oscillation and to improve the transient load stabilization.

Remark Connect the CIN and COUT to IC pins as close as possible (2 cm or less).

: Need for VO > VIN

D2 : Need a shottky barrier diode for VO < GND.

Note When output is off (VON/OFF = low level), OUTPUT pin should not be supplied higher voltage than VIN voltage

from external.

Caution When using the ÂµPC29S78GR and ÂµPC29S10GR, design your circuit and mounting with consid-

eration for heat radiation.
