Note:
1 Due to the diode partial pressure, the voltage of -Vo is lower than Vo
2 In order to obtain a more stable voltage, it is recommended that the output is greater than 1MA
3 -Vo cannot be used alone, or no voltage output.But you can just use Vo 
  
 
Applications
     
ADC/DAC/Operational Amplifier 
RS232 RS485 RS422 Bus
Audio equipment
LCD power supply
Instrumentation equipment
MCU Board

Instrumentation multimeter
Wifi/Router/Ethernet devices 
      
Attention :
    
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
  
Q & A:
  
Q : Why output voltage is less than the nominal voltage
A : Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low
