If this resistor is inserted, it can reduce the control current when the control voltage is high. The applied voltage to control pin 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. Ver.2014-02-07 -5- NJW4186 *Feed back Resistance R1 The output voltage may rise against the set point by the leak current from the VOUT pin at high temperature when this resistance is set too big. Conversely, the current flowing to R1 grows big when R1 is set too small, and make the consumption current increase. From the above, recommend 5k to 500k as a set range of R1. But, the output noise voltage tends to increase with the resistance value of R1 become small. Especially, In the case of low output voltage setting such as VOUT=2.0V, there is the possibility that the output voltage becomes unstable in the condition of recommended output capacitor (Co=4.7uF) and too small feedback resistor (R1). In that case, It can improve by making Co or R1 bigger. Show a characteristic example when changed a condition at the time of the Vo=2.0V / 5.0V setting for reference.

Therefore, use the recommended CIN value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and should connect between GND and VIN 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 VOUT 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. -8- Ver.2014-02-07 NJW4186 *The notes of the evaluation when output 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 Vo pin and the GND or using output condensers that have ESR more than 2ohrm like a tantalum or aluminum electrolytic capacitor.(see below figure) (a)In case of insert Schottky barrier diode between VOUT pin- GND VIN VIN VOUT VOUT SBD NJW4186 VADJ GND (b) In case of using the electrolysis condenser or insert series resistance VIN VIN VOUT VOUT NJW4186 VADJ Connecting resistance(2ohrm or more)in series.
