LP5907: About Dropout voltage(VDO) of X2SON PKG

Hide

Part Number: LP5907

Hi Team,

 

Our customer would like to know the maximum value of dropout voltage at Iout=100mA.

Could you please let us know if you have any information?

    Hi Kanemaru,

    As you can see in Figure 18, dropout is linear with regards to current.  As such we can calculate the expected maximum through ratios.  For example, the maximum dropout for the SOT-23 package is 250mV at 250mA of current; therefore, the expected maximum dropout at 100mA of current is 100mV for the SOT-23 package.

    Very Respectfully,

    Ryan

    Hi Ryan-san,

     

    Thank you for your prompt reply.

    According to the datasheet, the dropout voltage of SOT23 and X2SON is the same value.

    So, I understand that the expected maximum dropout at 100mA of current is 100mV for the X2SON package.

    Is my understanding correct?

     

    Regards,

    Kanemaru

    Hi Kanemaru-san,

    Correct as the SOT23 and X2SON have the same maximum dropout value, the same ratio applies to both packages.

    Very Respectfully,
    Ryan
