TPS7A8300: TPS7A8300RGRR

Part Number: TPS7A8300


I would like to know whether the designs given below can be used in the LDO (TPS7A8300RGRR) to produce the desired output voltages.


1. Input Voltage = 6.3V

2. Output Voltage = 5V

3. Maximum Current = 1.5A


1. Input Voltage = 6.3V

2. Output Voltage = 3.3V

3. Maximum Current = 1A

  • Hi ,

    Schematic 1:

    the passives are connected and sized appropriately, and the schematic would function.

    Schematic 2:

    Similarly the schematic looks good.

    The only concern is power dissipation. Pushing 3W through the device if operated at non room temperature the device may begin to run into situations where it is cycling into and out of thermal shutdown. Designing your PCB around these instances will help alleviate these concerns.
