  LM2731: Can SHDN pin do soft-start function?

  TI Thinks Resolved

  Part Number: LM2731 I see SC4503 can do soft-start by connected SHDN pin on external Rss/Css. Can LM2731 do the same thing? https://www.semtech.com/uploads/documents/sc4503.pdf

  LM2731 Shutdown pin behaviour

  TI Thinks Resolved

  What is the behaviour of LM2731 when shutdown is pushed to GND? Vout is 0V or is the input Voltage, or is high impedance? I ask this to know if i need an external mosfet to disconnect the Vout power supply

  LM2731: Why does the Vout change bigger?

  TI Thinks Resolved

  Part Number: LM2731 Dears: From the datasheet when the VOUT is 12V, and the Iout is 500mA. However, when we test our board Vout will change bigger if the load is bigger. Could you kindly help to check the schematic and give some suggestions about...
