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 pins (C
VIN and VSS pins (C
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 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
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.
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 capacitance of the IC’s output block is small, the power supply fluctuation and load fluctuation characteristics
become worse.
equipment.
When the capacitance of the IC’s output block is small, if the power supply suddenly increases sharply, a
momentary overshoot may be output. It is therefore important to sufficiently evaluate the output voltage at power
application in the actual equipment.
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 6 in the
electrical characteristics and footnote *5) of the table.
