8-2. ON/OFF Control
By using the ON/OFF control function, ON/OFF of the output without connecting and disconnecting the input can be controlled.
ON/OFF Pin (9pin) has been connected with +Vin terminal internally by the resistance of 22kΩ.
When not using the ON/OFF control, keep the ON/OFF pin open.

Short (0 to 0.8V
8-3. Adjusting Output Voltage
When using at 1.5V without adjusting output voltage, keep Trim pin (8pin) open. By connecting a resistor between Trim (8pin)
and –Sense pin (7pin) , the output voltage can be adjusted within the range of 0.6-1.5V. Connect –Sense pin to GND (6pin).
When adjusting the output voltage, place the Rx close to the converter and make the wiring of Rx as short as possible. If the
Trim pin catches noise, malfunction may occur.
To calculate the external resistance, please refer to the equation below. After calculating the external resistance, please
check the output voltage and adjust the resistance value.
