*In the case of using a resistance "R" between VIN and control.
If this resistor is inserted, it can reduce the control current when the control voltage is high.
The applied voltage to control terminal should set to consider voltage drop through the resistor “R” and the minimum
control voltage for ON-state.
The VCONT (ON) and ICONT have temperature dependence as shown in the "Control Current vs. Temperature" and "
Control Voltage vs. Temperature" characteristics. Therefore, the resistance "R" should be selected to consider the
temperature characteristics.
*Input Capacitor CIN
Input Capacitor CIN is required to prevent oscillation and reduce power supply ripple for applications when high
power supply impedance or a long power supply line.
Therefore, use the recommended CIN value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and
should connect between GND and the VIN pin as shortest path as possible to avoid the problem.
*Output Capacitor CO
Output capacitor (CO) will be required for a phase compensation of the internal error amplifier.
The capacitance and the equivalent series resistance (ESR) influence to stable operation of the regulator.
Use of a smaller CO may cause excess output noise or oscillation of the regulator due to lack of the phase
compensation.
On the other hand, Use of a larger CO reduces output noise and ripple output, and also improves output transient
response when rapid load change.
Therefore, use the recommended CO value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and
should connect between GND and the VOUT pin as shortest path as possible for stable operation
The recommended capacitance depends on the output voltage rank. Especially, low voltage regulator requires larger
CO value.
In addition, you should consider varied characteristics of capacitor (a frequency characteristic, a temperature
characteristic, a DC bias characteristic and so on) and unevenness peculiar to a capacitor supplier enough.
When selecting CO, recommend that have withstand voltage margin against output voltage and superior
temperature characteristic.

*The notes of the evaluation when the VO pin is shorted to GND
When evaluated short circuit test, the IC may break down because of regenerated energy by the parasitic inductance
included in wiring pattern.
It phenomenon appears conspicuously when output voltage is high(Vo=8.0V or more)or connected to inductive load.
In case of short circuit in actual application, not likely to destruction of IC because of some of Resistance exist
between load.
If happened above phenomenon by the short circuit test with the actual application, recommend connecting schottky
barrier diode(SBD) between the VO pin and GND or using output capacitors that have ESR more than 2Ω like a
tantalum or aluminum electrolytic capacitor.(see below figure)
