SUPER LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR
Precautions
• Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting an
• 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 the leakage current from a driver when a series regulator is used at
• 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 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
• If the output capacitance is small, power supply’s fluctuation and the characteristics of load fluctuation become worse.
• 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 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 11 in “
