  • TPS7A57: TPS7A57 ENABLE PIN RESISTOR DIVIDER

    TI Thinks Resolved
    Part Number: TPS7A57 Hi, We are using TPS7A57 for our design. Voltage for Enable pin in TPS7A57 is given as 0.68V in datasheet and we are using a sequencer which has a enable high voltage for 2.4V from which we are going to enable TPS7A57 . Can you please…

  • TPS7A57: REF_PIN CTRL MECHANISM

    TI Thinks Resolved
    Part Number: TPS7A57 We have used this LDO in our design and below is sch for for circuit implementation. Initially this regulator o/p should be set it to 1.1V and then after 20mS it should set it to 2.5V. To implement this, we have used the MOSFET circuit…

  • TPS7A57: Thermal design

    Resolved
    Part Number: TPS7A57 I have an EMI application where I need to use a linear regulator to generate 0.85V from a 5V input. This load is 2A continuous but may go to 3.5A for 500ms at initialization. So for heat dissipation, I need to consider 2A@4.2V or…
