Electrical Characteristics Common to All Products

out, and any drift in the electrical characteristic due to a rise in the junction temperature of the chip may be

disregarded.

Standard Application Circuit

• Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND.

The use of a monolithic ceramic capacitor (B Characteristic or X7R) of low ESR (equivalent series resistance)

is recommended. The IC may oscillate due to external conditions (output current, temperature, or the type of

the capacitor used). The type of capacitor required must be determined by the actual application circuit in

which the IC is used.

The notice in case of application

• The IC might be destroyed if a voltage greater than the input terminal voltage is applied to the output

terminal, or if the input terminal is connected to GND during operation. To prevent such an occurrence,

connect a diode as in the following diagram.

• There is a possibility that internal parasitic devices may be generated when momentary transients cause a

terminal’s potential to fall below that of the GND terminal. In such case, that the device could be destroyed.

The voltage of each terminal and any state must therefore never fall below the GND potential.
