  Due to the voltage loses in the LM317 regulator chip, the input voltage should be at least 2V more than the required output voltage. T -> Output Pulse. R1 should be in range of 1KΩ to 1MΩ. Duty = High Period ÷ Total Period × 100. R1 & R2 should be between 1KΩ and 10MΩ. It is not possible to have Duty < 50% with this circuit.

  Devido a perdas de tensão no chip de regulação LM317, a tensão de entrada dever se pelo menos 2V mais do que a tensão de saída necessária. 
   
  T -> Pulso de saída. R1 deve estar entre 1KΩ e 1MΩ. 
   
  Duty = Período Alto ÷ Período Total × 100. R1 e R2 devem estar entre 1KΩ e 10MΩ. Não é possível ter o Duty < 50% com este circuito.
