DATA SHEET
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)

: 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.
: 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 consid-
eration for heat radiation.
