Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hey Yuki,
This is not something that has been tested or known as it is outside of recommended operating conditions. We strongly recommend using a CF between 68pF and 100pF for output stability as stated in the datasheet. Additionally, if this is not used…
Part Number: LP3965 Team,
I see that the operating junction temperature of the below devices is listed in the datasheet, however the junction temp is calculated using Theta Ja values. our customer can only measure the case. can we provide the junction…
Part Number: LP3965 Other Parts Discussed in Thread: LP3962 Hi,
Where can I find the layout guidelines or an example layout for the LP3965EMP-ADJ/NOPB LDO?
Regards,
Prachi
Other Parts Discussed in Thread: LP3965 , LP3855-ADJ Hi!
I've made a power source(out 1.3V & from Vin(3.3V)) with LP3965.
I think everything is o.k. in conditions.
But if load current is big, output voltage drops like a ramp.
Because the pass…
Part Number: LP38512 Other Parts Discussed in Thread: LP3965 Hello,
In the customer, the inrush current is larger than the short protection current for LP3965 and LP38512. Please see the following conditions as inrush current. Is this current acceptable…
Other Parts Discussed in Thread: LP3965 In LP3965 datasheet, the input capacitor is limited by the following formula.
CIN ESR (m ohm) / CIN (μF) =< 1.5
If it deviates from this condition, how does the device operate?
Hello Donald san,
I apologize for a confusion.I need ThetaJP data. Please ignore the airflow and boards information of my previous post.
Best Regards,

Hi Charles,
Some costumers have used that approach in the past and it has worked fine.
1) Slowing V_SD slew rate will reduce the inrush current charging the system so is less likely that the control system will overshoot before reaching steady state. …
