BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC29S00 Series
LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF FUNCTION
The µPC29S00 series is a low dropout regulator which has 100 mA capable for the output current. This series
features ON/OFF function to control output voltage.
The µPC29S00 series is suitable for NEC’s single chip microcontroller which have on-chip flash memory. The
µPC29S00 series is use of erasing and writing data on its flash memory.
FEATURES
• ON/OFF control function (Active high)
• High accuracy output voltage : ±2% (7.8 V output)
• Output current excess of 100 mA
–2% to +1% (10 V output)
• Surface mount device package
• On-chip all kinds of protection circuit
: 4-pin plastic SIP (TO-126 Gullwing) (7.8 V output)
8-pin plastic SOP (225mil) (7.8 V output, 10 V output)

When operating junction temperature rises up to 150°C, the internal circuit shutdown output voltage.
Caution Exposure to Absolute Maximum Ratings for extended periods may affect device reliability;
exceeding the ratings could cause permanent damage. The parameters apply independently. The
device should be operated within the limits specified under DC and AC Characteristics.

CIN
D2
: 0.1 to 0.47 µF. 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 µF 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
: 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 µPC29S78GR and µPC29S10GR, 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 µPC29S00 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.

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 µPC29S00 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 µPC29S00 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.

purposes in semiconductor product operation and application examples. The incorporation of these circuits,

• While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. 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.
