DESCRIPTION
The
PC29M33A,
PC29M05A of low dropout voltage three terminal positive regulators is constructed with PNP output
transistor. The
PC29M33A,
PC29M05A feature the ability to source 0.5 A of output current with a low dropout voltage
of typically 0.5 V.
The power dissipation of the
PC29M33A,
PC29M05A can be drastically reduced compared with the conventional
three terminal positive voltage regulators that is constructed with NPN output transistor. Also, this series corresponds to
the low voltage output (3 V, 3.3 V) which is not in the conventional low dropout regulators (
PC24M00A series).
FEATURES

Note Internally limited. When the operating junction temperature rises over 150
C, the internal circuit shuts down the
output voltage.
Caution If the absolute maximum rating of any of the above parameters is exceeded even momentarily, the
quality of the product may be degraded. In other words, absolute maximum ratings specify the
values exceeding which the product may be physically damaged. Be sure to use the product with
these ratings never exceeded.

OUTPUT
C
IN
: 0.1
F or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be sure
to connect C
IN
to prevent parasitic oscillation. Use of a film capacitor or other capacitor with excellent voltage and
temperature characteristics is recommended. If using a laminated ceramic capacitor, it is necessary to ensure
that C
IN
is 0.1
F or higher for the voltage and temperature range to be used.
C
OUT
: 47
F or higher. Be sure to connect C
OUT
to prevent oscillation and improve excessive load regulation. Place
C
IN
and C
OUT
as close as possible to the IC pins (within 2 cm). Also, use an electrolytic capacitor with low
impedance characteristics if considering use at sub-zero temperatures.
D
1
: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.
D
2
: If the OUTPUT pin has a lower voltage than the GND pin, connect a Schottky barrier diode.
Caution Make sure that no voltage is applied to the OUTPUT pin from external.

Pre-heating temperature: 120C or below (Package surface temperature).
WS60-00-1
Partial Heating Method
Pin temperature: 300C or below,
Heat time: 3 seconds or less (Per each side of the device).
Caution Apply only one kind of soldering condition to a device, except for "partial heating method", or the
device will be damaged by heat stress.

Process
Conditions
Wave soldering
(only to leads)
Solder temperature: 260
C
or below,
Flow time: 10 seconds or less.
Partial heating method
Pin temperature: 300

NOTES ON USE
When the
PC29M33A,
PC29M05A are used with an input voltage that is lower than the value indicated in the
recommended operating conditions, a large quiescent current flows through the device due to saturation of the transistor
of the output stage. (Refer to the I
BIAS
(I
BIAS(S)
) vs. V
IN
curves in TYPICAL CHARACTERISTICS).
These products have saturation protector, but a current of up to 80 mA MAX. may flow through the device. Thus the
power supply on the input side must have sufficient capacity to allow this quiescent current to pass when the device starts
up.

The information in this document is current as of May, 2001. The information is subject to change
without notice. For actual design-in, refer to the latest publications of NEC's data sheets or data
books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all products
and/or types are available in every country. Please check with an NEC sales representative for
availability and additional information.
No part of this document may be copied or reproduced in any form or by any means without prior
written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document.
NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of
third parties by or arising from the use of NEC semiconductor products listed in this document or any other
liability arising from the use of such products. No license, express, implied or otherwise, is granted under any
patents, copyrights or other intellectual property rights of NEC or others.
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 customer's equipment shall be done under the full
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third
parties arising from the use of these circuits, software and information.
While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as
redundancy, fire-containment, and anti-failure features.
NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor product 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 and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
NEC (as defined above).
