Precautions
Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting
an output capacitor between the VOUT and VSS pin (CL) and a capacitor for stabilizing the input between VIN and
VSS pin (CIN), the distance from the capacitors to these pins should be as short as possible.
Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less).
Note that the output voltage may increase due to the leakage current from a driver when a series regulator is used at
high temperature.
Generally a series regulator may cause oscillation, depending on the selection of external parts. The following
conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual usage
conditions for selection, including evaluation of temperature characteristics. See “(5) Example of Equivalent Series
Resistance vs. Output Current Characteristics (Ta = 25
°C)” in “
Reference Data” for the equivalent series
resistance (RESR) of the output capacitor.
Input capacitor (CIN) :
1.0
μF or more
Output capacitor (CL) :
1.0
μF or more
The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small
or an input capacitor is not connected.
If the output capacitance is small, power supply’s fluctuation and the characteristics of load fluctuation become worse.
Sufficiently evaluate the output voltage’s fluctuation with the actual device.
A momentary overshoot may be output when the power supply suddenly increases, and the output capacitance is
small. It is therefore important to sufficiently evaluate the output voltage at power application in actual device.
The application conditions for the input voltage, output voltage, and load current should 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.
In determining the output current, attention should be paid to the output current value specified in Table 10 in “
Electrical Characteristics” and footnote *5 of the table.

this IC of patents owned by a third party.
