µPC2250 SERIES
LOW-SATURATED STABILIZED POWER SUPPLY WITH SYSTEM RESET PIN
DESCRIPTION
The µPC2250 series is a collection of low-saturated 4-pin stabilized power supplies with a pin that outputs a reset
signal when a drop in the input voltage is detected.
Because the reverse leakage current of these power supplies is about 1 µA even if a voltage is applied to the
output pin when the input voltage is cut off, these power supplies are ideal for systems with on-board
microprocessors requiring battery backup.

Note The total loss is limited by an internal circuit. Where TJ > 150°C, an internal protection circuit cuts off the
output.
Caution If any of the parameters exceeds the absolute maximum ratings, even momentarily, the quality of
the product may be impaired. The absolute maximum ratings are values that may physically
damage the product(s). Be sure to use the product(s) within the ratings.

CIN
: Determine the capacitance depending on the line between the power supply smoothing circuit and input pin.
Be sure to connect this capacitor to prevent abnormal oscillation. Use of a capacitor, such as a film
capacitor, with excellent voltage and temperature characteristics is recommended. Note that some
laminated ceramic capacitors have poor temperature and voltage characteristics. When using a laminated
ceramic capacitor, the capacitance must be stable in the voltage and temperature ranges used.
: Must be 10 µF or more. Be sure to connect this capacitor to prevent oscillation and to improve transient
load stability.
CO
Connect CIN and CO as close to the IC (within 1 to 2 cm) as possible.
D1, D2 : Connect Schottky barrier diodes (with a low forward voltage) if the voltage on the OUTPUT and RESET pins
is lower than that on the GND pin.

Caution The recommended operating range may be exceeded without causing any problems provided
that the absolute maximum ratings are not exceeded. However, if the device is operated in a way
that exceeds the recommended operating conditions, the margin between the actual conditions
of use and the absolute maximum ratings is small, and therefore thorough evaluation is
necessary. The recommended operating conditions do not imply that the device can be used
with all values at their maximum values.

NOTES ON CORRECT USE
Keep the output current of the µPC2250 series to within lO (steady-state current) in Figure 1 at the operating
junction temperature (TJ).
Keep the output current, including the inrush current to the output capacitor, to within IORUSH in the figure when
starting the circuit.
If these current limits are exceeded, the output voltage may not rise to the specified level because of the operation
of the overcurrent limiter circuit.

• Descriptions of circuits, software, and other related information in this document are provided for illustrative
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.
