µPC24A00 Series
THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
The µPC24A00 Series is a low dropout voltage three terminal regulator that has realized a minimum voltage
differential between the I/O of no more than 1 V when the output current is 2 A through the employment of a PNP
transistor at the output stage.
Due to its ability to achieve a greater reduction in the power loss compared with conventional three-terminal
regulators, the µPC24A00 Series is ideal for use as the secondary side smoothing circuit of a power supply.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.

CIN:
0.1 to 0.47 µF. Be sure to connect to prevent abnormal oscillation. When using capacitors, film capacitors with
excellent voltage and temperature characteristics are recommended. Be aware that some monolithic ceramic
capacitors have inferior temperature and voltage characteristics. When using a monolithic ceramic capacitor,
CIN requires a capacitor that can secure this capacity within the voltage and temperature range used.
COUT: 10 µF or higher. Be sure to connect to prevent oscillation and to improve transient load stabilization.
Remark Connect CIN and COUT as close as possible to the IC pins (within 2 cm).

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.

RECOMMENDED SOLDERING CONDITIONS
The µPC2400 Series should be soldered and mounted under the following recommended conditions.
For the details of the recommended soldering conditions, refer to the document SEMICONDUCTOR DEVICE
MOUNTING TECHNOLOGY MANUAL (C10535E).
For soldering methods and conditions other than those recommended below, contact your NEC sales
representative.
Through-Hole Device
µPC24A05HF, 24A12HF, 24A15HF: 3-Pin Plastic SIP (MP-45G) (Isolated TO-220)
Process
Wave soldering
(only to leads)
Conditions
Solder temperature: 260°C or below, Flow time: 10 seconds or less.
Caution Apply wave soldering only to the pins and be careful not to bring solder into direct contact with the
package.
CAUTION ON USE
• In the µPC24A00 Series, if the output is short-circuited at VIN ≥ 20 V, the output may not be restored after the short-
circuit is cancelled. In this case, restore the output by lowering and then reapplying VIN.
• If a lower than recommended input voltage is used in the µPC24A00 Series, a large circuit current will flow due to
the saturation of the output stage transistor (refer to the reference characteristic curve of the IBIAS − VIN
characteristics). The capacitance for the input side power supply therefore needs to be only enough to enable the
current to flow in this circuit at startup. Note also that a resistor cannot be inserted at the GND pin to adjust the
output voltage.

rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other

• 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,
software, and information in the design of the customer's equipment shall be done under the full responsibility
of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third
parties arising from the use of these circuits, software, and information.
• 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.
