Precautions

• Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When

possible.

• Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less).

• 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.

1.0

μF or more

1.0

μF or more

Equivalent series resistance (ESR):

10

Ω or less

• 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.

• 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 7 of “

Electrical Characteristics”

and footnote *8 of the table.

• SII claims no responsibility for any disputes arising out of or in connection with any infringement by products

including this IC of patents owned by a third party.
