Hello Jiawei,
Here is an application note for how to design an external soft start circuit: /cfs-file/__key/communityserver-discussions-components-files/138/1616.Soft_2D00_Start-Circuits-for-LDO-Linear-Regulators_5F00_slyt096_5B00_1_5D00_.pdf

Other Parts Discussed in Thread: TPS74701 Using the TPS74701 LDO with a the Enable controlled by a seprate signal (not Vin or Vbias). Ven = 1.8V, Vin = 1.3V, Vbias = 3.3V. Is there a concern if Ven is applied before Vin or Vbias?
I see in the data sheet…
Hi,
As per the "Pin Functions" table in the datasheet, if the SS pin is left unconnected, the soft start time is set to 200us. However, as per the table 3 in the datasheet, it should be 100us.
Please confirm which value is correct.
Regards, …
Other Parts Discussed in Thread: TPS74701-Q1 Hello,
My customer requests us to provide the IBIS file for TPS74701-Q1.
The IBIS file is not place at ti.com device folder.
Please let me know where I can get the IBIS file for TPS74701-Q1.
Thank you,
Lloy…
Hi,
I'd like to know if the VDO spec is applied for all output range. Actually my customer want to set 1.0V output and so VDO(max)=120mV can be applied at 1.0V setting.

Part Number: TPS73 Other Parts Discussed in Thread: TPS745 , TPS74701 , TPS7A26 Hi,
We are looking for an alternative part of TPS7301QDG4. Is there any part pin to pin match it, even the output current is smaller than 500mA? we can evaluate the small current…
Other Parts Discussed in Thread: TPS74701 Hi all Would you mind if we ask TPS74701? Our customer is planning to use a TPS74701 and have the following question. <Question> Situation: The IN(Vin) pin (+1.8V) is asserted 2ms before the voltage at “Bias(Vbias3…
Sonoki-san,
TPS74701 does not have an active discharge for the output capacitor. The output capacitor will discharge through any load resistance and leakage paths. It is possible to make an external active discharge circuit with a FET and resistor.
Very…
Other Parts Discussed in Thread: TPS74701 Hi all Would you mind if we ask TPS74701? <Question> The datasheet shows "the TPS74701 is stable with output capacitors as low as 2.2 μF". So how much is the maximum vaule of the output capacitance…
