%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.
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.
