Remarks
No voltage, no matter how instantaneous, shall be applied beyond the absolute maximum voltage rating to this
product. If you apply any voltage over this limit the product characteristics will deteriorate or the product itself will
be destroyed. Even though it may continue operating for a while after the over-voltage event, its life will likely be
shortened significantly. Reliability and life of the module may degrade similarly if the maximum operating voltage
rating is continuously exceeded. This product is designed to operate within the maximum operating voltage rating
specification.

7. Operation information
7.1. Adjusting the Output Voltage
The output voltage can be adjusted from 0.7525V to 3.63V by connecting resistors between TRIM-pin(9,10Pin)
to GND(5,6)-pin.
The following equation gives the required external-resistor values to adjust the output voltage to the required
Vout.

7.4. Input External capacitor
It is recommended to connect a low-impedance electrolytic capacitor of 100μF or more at Vin terminal.
Smaller input capacitor may leads to an unstable operation of this product caused by input voltage
fluctuation. Please check the proper operation of it on your product when smaller input capacitor is used.
Using ceramic capacitors as input capacitor may cause an increase of output voltage, because input ripple
current flows through the external input capacitor and wiring resistance.
This phenomenon is affected by the position of external capacitors, the value of external capacitors and
voltage difference between Vin and Vout. Using low-impedance electrolytic capacitor will ease this problem.
Please check the proper operation of it on your product when ceramic input capacitor is used.

7.5. Output External capacitor
Ceramic capacitors are recommended as output external capacitor.
Using ceramic capacitors, small output variation and small ripple voltage are realized.
Output capacitor should be within 10μF to 1000μF. Output capacitor shall be placed near the
output terminal. When using plural capacitors, please make sure to place a capacitor of at least
47μF near the output terminal, and place other capacitors near the load.
When using LC output filter, please make sure to place a capacitor of at least 10μF near the output
terminal.

※Do not vibrate for the products on reflow.
Please need to take care temperature control because mounted parts may come off if the product are left
under the high temperature.
Do not reflow DC-DC converter as follows, because DC-DC converter may fall down from a substrate during
Substrate
reflowing.

14. Notice
14. 1.
Both input-side and output side, please make the wiring loop between plus and minus as small as possible.
The influence of a leakage inductance can be reduced.
14. 2. Please make the power line pattern as wide and short as possible.
The Following figure is an example of recommendable PCB design.

14. 3.
This product should not be operated in parallel or in series.
14. 4.
Please do not use a connector or a socket to connect this product to your product.
The electric characteristics may be deteriorated by the influence of contact resistance.
14. 5.
Be sure to provide an appropriate fail-safe function on your product to prevent secondary damage
that may be caused due to abnormal functional or failure of this product.
14. 6.
14. 7.
Inrush current protection is not a feature of this product.
Be sure not to warp your PCB over 90μm.
If not, the parts on the backside of this device touch on your PCB, and that may lead to cracks of the
backside parts or reliability deterioration of this device.

14. 9. Cleaning
Please use no-cleaning type flux and do not wash this product.
14.10. Storage
14.10.1. Please store the products in room where the temperature/humidity is stable and direct sunlight cannot
come in, and use the products within 6 months after delivery.
Please avoid damp and heat or such places where the temperature greatly changes, as water may
condense on this product, and the quality of characteristics may be reduced, and/or be the solderability
may be degraded.
If this product needs to be stored for a long time (more than 1 year), this product may be degraded in
solderability and/or corroded. Please test the solderability of this product regularly.
Baking before reflow process is unnecessary to store the products under 30℃,60%RH or less up to 6
months.
In case the storage condition is over above mentioned, if these are unpacked condition, please bake them
at 125℃±5℃/24hour. If these are packed in a tape, please bake them before soldering at 60℃±5℃
/168hour.
14.10.2. Please do not store this product in places such as :
A dusty place, a place exposed directly to sea breeze, or in an atmosphere containing corrosive gas
(Cl2,NH3,SO2,NOX and so on).

14. 11 Operational Environment and Operational Conditions
14. 11. 1. Operational Environment
This product is not water-, chemical- or corrosion-proof.
In order to prevent leakage of electricity and abnormal temperature rise of the product, do not operate
under the following environmental conditions:
(1) An atmosphere containing corrosive gas (Cl2, NH3, SO2, NOX and so on)
(2) A high-dust environment
(3) Under the exposure of direct sunlight
(4) A location where the likelihood of exposure to water or water condensation exists.
(5) A location exposed to ocean air
(6) Any locations similar to the above
14. 11. 2. Operational Conditions
Please use this product within specified values (power supply, temperature, input, output and load
condition, and so on). If the product is exposed to conditions outside of the specified values reliability of
the product may be adversely effected.
14. 11. 3. Note prior to use
Diminished reliability and/ or failure may result if the product is exposed to a high-level static charge,
over-rated voltage or reverse voltage. Please avoid the following conditions be avoided prior to use of
the product:
(1) Supply of power outside of rated values (see section 8)
(2) Supply of reverse power or inadequate connection of a 0 V(DC)line
(3) Electrostatic discharge from production line and/ or operator
