  • LP38690: SNS input resistance

    TI Thinks Resolved
    Part Number: LP38690 Hi, The LP38690 shows the SNS input stage to use an internal resistor divider R1/R2, but it does not spec the resistor values or input leakage. How large is the internal resistance R1+R2, and is there any other leakage spec? I am…

  • LP38690: Stability and Output Capacitor ESR

    Part Number: LP38690 I have a customer who is using a LP38690 with Vin = 6.6V from a 400kHz switching power supply and Vout = 5.0V. They are using a 4.7uF ceramic capacitor on the input and both a 4.7uF, 0603 located right at the output pin of the part and…

  • RE: LMS1585A: Design Review

    Hey Sonali, Your circuit looks correct. However, because the datasheet specifies polarized capacitors, it makes me think that this part may need a minimum ESR to be stable. There is no mention of it in the datasheet but it may be a safe choice to include…
