State of control pin:
“H” output is enabled.
“L” or “open” output is disabled.
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 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 though this product is designed stability works with wide range ESR of capacitor including low ESR
products.
