2 In use of ON/OFF CONTROL:

State of control terminal:

•“H”→ output is enabled.

•“L” or “open” → output is disabled.

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 0.01uF greater to avoid the problem.
