*Noise bypass Capacitance Cp
Noise bypass capacitance Cp reduces noise generated by band-gap reference circuit. Noise level and ripple rejection
will be improved when larger Cp is used. Use of smaller Cp value may cause oscillation.
Use the Cp value of 0.01μF greater to avoid the problem.
*In the case of using a resistance "R" between V
IN
and control.
If this resistor is inserted, the control current could be reduced 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 V
CONT (ON)
and I
CONT
have temperature dependence as shown in the "Control Current vs. Temperature" and "
Control Voltage vs. Temperature" characteristics. Therefore, the resistor "R" should be selected to consider the
temperature characteristics.

*Input Capacitor C
IN
The input capacitor C
IN
is required in order to prevent oscillation and reduce power supply ripple of applications when
high power supply impedance or a long power supply line.
Therefore, the recommended capacitance (refer to conditions of ELECTRIC CHARACTERISTIC) or larger input
capacitor, connected between V
IN
and GND as short path as possible, is recommended in order to avoid the problem.
*Output Capacitor C
O
The output capacitor C
O
is required for a phase compensation of the internal error amplifier, and the capacitance and
the equivalent series resistance (ESR) influence stable operation of the regulator.
If use a smaller output capacitor than the recommended capacitance (refer to conditions of ELECTRIC
CHARACTERISTIC), it may cause excess output noise or oscillation of the regulator due to lack of the phase
compensation. Therefore, the recommended capacitance or larger output capacitor, connected between V
OUT
and
GND as short path as possible, is recommended for stable operation. The recommended capacitance may be
different by output voltage, therefore confirm the recommended capacitance of the required output voltage.
Furthermore, a larger output capacitor reduces output noise and ripple output, and also improves Output Transient
Response when a load changes rapidly.
Selecting the output capacitor, should consider varied characteristics of a capacitor: frequency characteristics,
temperature characteristics, DC bias characteristics and so on. Therefore, the capacitor that has a sufficient margin of
the rated voltage against the output voltage and superior temperature characteristics, is recommended for C
O
.
