3. Nonlinearity (ΔN
L
)
ΔN
L
indicates the nonlinearity of the output voltage and is defined as the difference of the characteristic curve of
the output voltage and the approximated straight line shown below.
ΔN
L
is calculated using the following formula.

*1. The maximum deviation of the actual measurement of output voltage (B) and an approximated straight
line (A) in temperature within −20°C to +80°C. (An approximated straight line is taken as the straight line
from which the “a” becomes the minimum.)
*2. The difference of the output voltage within −20°C to +80°C.
4. Line Regulation (ΔV
OUT1
)
ΔV
OUT1
indicates the output voltage dependence on the input voltage. That is, the values express how the
output voltage changes, when input voltage is changed under the condition that output current is fixed.
5. Load regulation (ΔV
OUT2
)
ΔV
OUT2
indicates the output voltage dependence on the output current. That is, the values express how the
output voltage changes, when output current is changed under the condition that input voltage is fixed.

Precautions
• Wiring patterns for VDD pin, VOUT pin and VSS pin should be designed to hold low impedance.
• In this IC, if load capacitance of VOUT pin is large, VOUT pin voltage may oscillate. It is recommended not to
use the external capacitor between the VOUT and VSS pin. In case of using external capacitor, mount it near
the VOUT pin.
When connecting A/D converter etc. to the VOUT pin, input pin capacitance of A/D converter and the
parasitic capacitance component between wires are included as load capacitance.
To prevent oscillation, it is recommended to use the following output load condition.
Load capacitance of VOUT pin (C
L
) : 100 pF or less
• In this IC, if load resistance of VOUT pin is small, VOUT pin voltage may oscillate. It is recommended not to
use the external resistor between the VOUT and VSS pin.
When connecting A/D converter etc. to the VOUT pin, input resistance of A/D converter and the parasitic
resistance component between wires are included as load resistance.
To prevent oscillation, it is recommended to use the following output load condition.
Load resistance of VOUT pin (R
L
) : 500 kΩ or more

Caution The above connection diagram and constant will not guarantee successful operation.
Perform through evaluation using the actual application to set the constant.
• Please do not connect a pull-up resistor to the output voltage pin.
• The application condition for input voltage, output voltage and load current must not exceed the package
power dissipation.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
• Regarding the current at the output pin, refer to load regulation and footnote *1 in Table 5 to Table 6 “
Electrical Characteristics”.
• SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of the
products including this IC upon patents owned by a third party.
