Part Number: LP3965
Hi, support team
My customer has the questions as follow:
1. About LP3965-ADJ, datasheet said that: "To obtain a desired output voltage, can be used with R1 always a 10kΩ resistor."
Could you tell me the detailed reason of…
Part Number: LP3965 I'm Wakamatsu, Second Engineering Department, Sanwa Electronics Co., Ltd. Can you give me some advice on the following events? ・ Event The output voltage is about 2.75V in the circuit of the document. When pins 4-5 are short-circuited…
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…
Hi Prachi,
We have layout guidelines in the PCB LAYOUT section on page 11 of the current datasheet revision (SNVS066H). Further information is available in other sections to provide additional information for a specific topic such as the capacitor…
Based on what I see, I can only think of two things that would cause output current to go to zero : Thermal Shutdown, and Shutdown pin voltage.
The current spikes are from the output turning back on and recharging the output capacitor.
Thermal shutdown…
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?
Hi Gareth,
Please attached note DS16EV5110 EVM user guide. This document has schematic of this board as well.
