Preliminary TYPICAL APPLICATION (1) In the case where ON/OFF Control is not required: Connect control terminal to VIN terminal In case a resistance "R" is used, the quiescent current will be decreased. However, the but minimum operating voltage will be increase as well. Please refer to a figure of Output Voltage vs. Control Voltage.
