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. *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 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. Ver.2013-04-17 -5- NJW4185 *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 output pin - GND V IN V IN V OUT NJW 4185 V OUT SBD GND (b) In case of using the electrolysis condenser or insert series resistance VIN VIN VOUT VOUT NJW4185 Connecting resistance(2ohrm or more)in series.
