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.
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.因LM317稳压器芯片中的电压损耗，输入电压应至少高于所需输出电压2伏特。
T -> 输出脉冲R1应处于1KΩ-1MΩ范围内。
占空比(Duty) = 高周期(High Period) ÷ 总周期(Total Period) × 100. R1 & R2应在1KΩ-10MΩ之间。 电路的占空比不可能 > 50% 。 -
