Precautions
• Wiring patterns for the VIN pin, VOUT pin and GND pin should be designed so that the impedance is low. When
• Note that the output voltage may increase when a series regulator is used at low load current (10 µA or less).
• Note that the output voltage may increase due to driver leakage when a series regulator is used at high temperatures.
• Generally a series regulator may cause oscillation, depending on the selection of external parts. The following
• The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or
• It is important to sufficiently evaluate the output voltage fluctuation due to the power supply fluctuation and load
• If the power supply suddenly increases sharply, a momentary overshoot may be output. It is therefore important to
• The application conditions for the input voltage, output voltage, and load current should not exceed the package power
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
• In determining the output current, attention should be paid to the output current value specified in Table 6 in the “
