CIN
COUT
CIN
: 0.1 to 0.47 F. 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.
COUT
: 10 F 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). D1 D2 : Need for VO > VIN : 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 PC29S78GR and PC29S10GR, design your circuit and mounting with consideration for heat radiation.

Caution If the Absolute Maximum Rating is not exceeded, there is no problem for using recommended operating range or more. Use and evaluate the PC29S00 Series since the leeway is decreased with the Absolute Maximum Rating. Moreover, the recommended operating range is not prescribed to use when all parameters are maximum value. ELECTRICAL CHARACTERISTICS

Through-hole device
PC29S78H: 4-pin plastic SIP (TO-126)
Process Wave soldering (only to leads) Partial heating method Conditions Solder temperature: 260C or below, Flow time: 10 seconds or less. Pin temperature: 300C or below, Heat time: 3 seconds or less (per each lead).
Caution For through-hole device, the wave soldering process must be applied only to leads, and make sure that the package body does not get jet soldered.
CAUTION ON USE
When using the PC29S00 series at the input voltage which is lower than in the recommended operating condition, the big quiescent current flows through device because the transistor of the output paragraph is saturated (Refer to IBIAS (IBIAS (s)) vs VIN curves in TYPICAL CHARACTERISTICS). The PC29S00 series has saturation protection circuits, but they sometimes need about 50 mA current. Therefore the power supply on the input needs the enough current capacity to pass this quiescent current when the device start-up.

To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. * NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance.
