Though the I

decreases by inserting "R" to between Control terminal and V

increased due to the resister "R".

* 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.
* 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 0.1µF 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.
