TPS79901QDRVRQ1

While testing the load transient response of the IC TPS79901QDRVRQ1, with load 50mA, there is a drastic response. In datasheet, there is no specific data describing this issue. For your reference I have attached the waveform captured.

LOAD 50mA. Vin = 3.3V, Transient Vout Variation = 503.75mV

What is the acceptable load transient variation?

    Hi Vishali,

    This does not really look like a regular load transient. What kind of lead are you using? Is it an electronic load? 

    Can you capture the load transient waveform and include the load current as well as the input voltage? 

    Regards,
