Connect control terminal(1Pin) to VIN terminal(5Pin)

When a resistance “R” is connected, the quiescent current decreases, but minimum operating voltage

increases. Please refer to a figure of Output Voltage vs. Control Voltage.

When the control terminal is “H”, it is ON.

When the control terminal is “L” or “open”, it is OFF.

✱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. Please refer to the typical

characteristics to determine the value.

Use of smaller CP value may induce oscillation.

Please make sure to use CP value of greater than 0.1uF to avoid the problem.
