Precautions
• Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting
• Note that the output voltage may generally increase when a series regulator is used at low load current (0.1 mA or
• Note that the output voltage may generally increase due to the leakage current from a driver when a series regulator
• Note that the output voltage may increase due to the leakage current from a driver even if the ON/OFF pin is at the
• Generally series regulators may oscillate, depending on the selection of external parts. The following conditions are
• The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitance of the
• It is important to sufficiently evaluate in an actual device output voltage fluctuations caused by power supply or load
• A momentary overshoot may be output when the power supply suddenly increases, and the output capacitance is
• The application conditions for the input voltage, output voltage, and load current should not exceed power dissipation
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
