Remarks
*No voltage, no matter how instantaneous, shall be applied beyond the absolute maximum voltage rating to this
product. If you apply any voltage over this limit the product characteristics will deteriorate or the product itself will
be destroyed. Even though it may continue operating for a while after the over-voltage event, its life will likely be
shortened significantly. Reliability and life of the module may degrade similarly if the maximum operating voltage
rating is continuously exceeded. This product is designed to operate within the maximum operating voltage rating
specification.

9 .15 Thermal Derating
The above derating limits apply to this product soldered directly to 101.6*180mm*1.6mm PCB (double-sided,
with 70um copper). Any adjacent parts of high temperature may cause overheating. For reliable operation,
please ensure that the IC temperature of this product is maintained below 120°C and the inductor temperature
is below 119°C.
9.2 Pin Description
9.2.1 Trimming (Adjusting) the Output Voltage
The output voltage can be adjusted from 0.8V to 1.8V by connecting a resistor between TRIM-pin(8Pin) to
GND-pin(Pin 3 is recommended for accurate Vout setting).
The following equation gives the required external-resistance value to adjust the output voltage to the required
Vout.
