  • LP3873: Capacitance of C51

    Part Number: LP3873 Hello team, Our customer used to LP3873ESX-3.3/NOPB. Is it OK to insert a 10uF ceramic capacitor in C51 below to provide a delay between the rising edge of +5V and the rising edge of +3.3V? Is there anything they should pay attention…

  • LP3873: LP3873-1.8

    Resolved
    Part Number: LP3873 Datasheet states: TURN-ON CHARACTERISTICS FOR OUTPUT VOLTAGES PROGRAMMED TO 2.0V OR BELOW As Vin increases during start-up, the regulator output will track the input until Vin reaches the minimum operating voltage (typically about…

  • LP3873: Shutdown pin is 3.3V while the VIN is 0V

    TI Thinks Resolved
    Part Number: LP3873 Hi Team, A customer would like to know if there will be issues if the shutdown pin has a voltage input of 3.3V while the VIN is 0V. He also wants to know the worst case overshoot of the device upon power on. Regards, Danilo

  • RE: Dropout voltage of LM350K STEEL/NOPB @ 3A out out current

    Hello Madiwalesh, The LM350 Minimum Operating Vin to ensure 3A output = Vout+3V = 5.0V+3.0V = 8.0V That will cause 6W (3A x 3V) to be dissipated in the K (TO-3 / NDS) package. A heat sink will be needed. I do suggest that you consider a Buck SMPS as it…
