State of control terminal:

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 0.01
µ
F greater to avoid the problem.
Input Capacitance C
IN
Input Capacitance C
IN
is required to prevent oscillation and reduce power supply ripple for applications with high
power supply impedance or a long power supply line.
Use the C
IN
value of 0.1
µ
F greater to avoid the problem.
C
IN
should connect between GND and V
IN
as short as possible.
In the case of using a resistance "R" between V
IN
and control.
The current flow into the control terminal while the IC is ON state (I
CONT
) can be reduced when a pull up resistance
"R" is inserted between V
IN
and the control terminal.
The minimum control voltage for ON state (V
CONT (ON)
) is increased due to the voltage drop caused by I
CONT
and the
resistance "R". The I
CONT
is temperature dependence as shown in the "Control Current vs. Temperature"
characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds
the V
CONT (ON)
over the required temperature range.
