BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC2933A, 2905A
THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR
DESCRIPTION
The µPC2933A, 2905A of low dropout voltage three terminal positive regulators is constructed with PNP output
transistor. The µPC2933A, 2905A feature the ability to source 1 A of output current with a low dropout voltage of typically
0.7 V.
The power dissipation of the µPC2933A, 2905A 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 ( µPC2400A series).
FEATURES
• Output current in excess of 1.0 A
• Low dropout voltage VDIF = 0.7 V TYP. (at IO = 1 A)
• On-chip overcurrent and thermal protection circuit
• On-chip output transistor safe area protection circuit

Note Internally limited. When the operating junction temperature rises over 150°C, the internal circuit shuts down the

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.

CIN: 0.1 µF or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be sure
to connect CIN 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 CIN is 0.1 µF or higher for the voltage and temperature range to be used.
★ COUT: 47 µF or higher. Be sure to connect COUT to prevent oscillation and improve excessive load regulation. Place
CIN and COUT 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.
D1: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.
D2: 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.

µPC2933A, 2905A
NOTES ON USE
When the µPC2933A, 2905A 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 IBIAS (IBIAS(S)) vs. VIN 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.

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).
