TPS7A24: Optimal value for output capacitor of TPS7A2401DBVR

Part Number: TPS7A24

Recommended values for output capacitors
The data sheet has a range of MIN: 1uF, NOM: 2.2uF, MAX: 100uF.
Under what conditions is this determined?
(For example, it depends on the output current)

Also, what is the optimum value when the output current is 10mA?
Please tell me where to read from the data sheet.

  • Hello,

    If you go to 6.2 "Electrical characteristics" you can see a lot of information with a 2.2 uF capacitor but the current is not 10 mA. All of the tests run are with a 1mA current. The values would be different using a 10mA output current.

    Also, 6.3 has good information on the operating conditions. There is a wide range of output capacitance. 

    In 8.1.3 it says that an effective output capacitance should not exceed 50 uF. 

    Also, optimum value is really depending upon the application and the results you are trying to achieve.

    Conditions: 

    Temperature, Vin and Vout, output current. 

    The picture I have attached is on page 3. 

    Please let me know if you have any other questions. 

    Thank you,

  • Also, 

    The range of capacitors is in accordance with the range of output current. So the 0 -200 mA works alongside the 1-100 uF.

    Thank you,
