of the line between the regulator and the INPUT pin. Use of a film capacitor or other capacitor with first-rate

voltage and temperature characteristics is recommended. If using a laminated ceramic capacitor, it is

μ F or higher for the voltage and temperature range to be used.

capacitor, please note following items.

μ F or higher for the voltage and temperature range to be used.

• In case of using laminated ceramic capacitor, it is easy to become state of parasitic oscillation. Because

ESR of laminated ceramic capacitor is very low. Therefore, the capacitor and load condition (output current)

which fulfill the condition of the stable operation area of ESR shown below are recommended.

• Stable Operation Area as below is regulated under condition of which this product is not on a substrate.

Therefore impedance on substrate is not considered.

: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.

: If the OUTPUT pin has a lower voltage than the GND pin, connect a Schottky barrier diode.

Note

Caution Make sure that no external voltage is applied to the OUTPUT pin.
