TPS7A7300: Typical dropout voltage when Iout = 2A

Part Number: TPS7A7300
Other Parts Discussed in Thread: TPS7A7200

Hello team,

My customer requested the typical dropout voltage at 2A Iout. In datasheet, there is the only data at 3A condition. Can you please provide me the typical dropout data at Iout = 2A(both 3.3V>= and 3.3V<)?

Best Regards,

Austin

    Hi Austin,

    This would require additional characterization to get, so we do not have data to share with Iout = 2A. However, the Iout = 3A condition represents a worse-case scenario in the context of dropout voltage, so it is guaranteed that the dropout voltage will also be within the maximum specifications when Iout = 2A. 

    Regards,

    Hi Nick,

    The customer would like to use TPS7A7300 instead of TPS7A7200 due to the shortage issue. From the datasheet, there is a dropout voltage vs output current graph. Can you check the exact data? The customer want to compare Vdo of TPS7A7300 with TPS7A7200.

    Best Regards,

    Austin

    Hi Austin,

    TPS7A7200 and TPS7A7300 us the same die - the only difference is that TPS7A7300 is tested at final test up to 3A and has a higher current limit. As such, the typical plots (e.g. Figure 5) are the same between the parts.
