Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Applications
• Serial printers, line printers, office automation equipment.
• Floppy disk units, portable VCRs.
Features
• 2 outputs for microconputer power supply (5V) and motor drive power supply (12V) and capable of delivering 2
regulated voltage outputs form 1 rectifier.
• Chopper type permitting high efficiency, and separate
excitation type oscillator common to 2 outputs causing
no beat trouble.
• Independent overcurrent protectors for 2 outputs (Foldback
characteristics)
• External signal-used output cutoff function (Output 2).
• High-precision setting of output voltage eliminating the
need to use a variable resistor for adjustment.
• One input/output GND line making it possible for other
negative voltage to be used jointly.
• A ne gati v e v oltage regulator (–5V, –12V, etc.) can be connected externally.
• Output voltage, output current constituting a series.

· Since pin 12 is grounded to the substrate, noise may be affected when a heat sink is connected to the FG (Frame
Ground), GND line, etc.
In this case. bring the heat sink to floating state or use an insulating sheet.

Test Circuit
* The N.C. pin (pin 18) must not be used as a relay pin for other line, pin.
* Pins connected inside the IC (6-7, 8-9, 10-11, 14-15, 16-17) must be also connected on the printed circuit board.
Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
