Part Number: LP2992 Tool/software: WEBENCH® Design Tools Hello together,
I have a question about dimensioning of capacities at LP2992. My switching regulator has the switching frequency of 330KHz and ripple noise of 30mVp-p. I have put this values into…
Part Number: LP2992 Hi,
The following is written on the datasheet of 7.4.2.
"If this feature is not to be used, the ON/OFF input must be tied to VIN to keep the regulator output on at all times. "
"To prevent mis-operation, the turnon (and turnoff…
Part Number: TPS723 Other Parts Discussed in Thread: LP2992 , Hello together,
I am using two switching regulators in a parallel application to reduce the input voltage from 24V to ±3.3V. Then I connect the positive output +3.3V from the switching regulator…
Part Number: LP2992 Hi ,
Please confirm if we can use the part "LP2992AIM5-3.3/NOPB" as a drop in replacement for the part "LP2985-33DBVR" (both functional and pin to pin). We require the load current to be 250mA .Pls help us on it or ls share any other…
Part Number: LP2992 Hello team,
I have a question about LP2992 ESR requirement for output capacitor.
Capacitor's ESR has frequency characteristics. What frequency range should we see for the ESR requirement?
Best regards,
Part Number: LP2992 Hello,
In my company we have been using LP2992AIM5-5.0/NOPB as a regulator in an equipment we have been producing for more than 5 years. In the last batch we have produced we had to deal with a problem with this part: It worked fine…
Part Number: LP2992 Hello Sir,
LP2992 Tj max is 125 degree C.
If our design is 12Vin and 3.3Vout , 65mA
PD is 0.56W so that refer to Theta JC is 122 for SOT23 package .
Will cause IC internal temp rising 69 degree C .
System ambient Temp budget will…
Part Number: LP2992 Other Parts Discussed in Thread: LP2985 Hi,
Both LP2992 and LM2985 are listed with thermal shutdown feature, however there is no specific thermal shutdown threshold or tolerance in the specification. Can you advise the details?
…
Part Number: LP2992 Hello,
The following is stated page 1 of the LP 2992 datasheet: "The LP2992 is stable with output capacitor equivalent series resistance (ESR) as low as 5 mΩ, which allows the use of ceramic capacitors on the output."…
Part Number: LP2992 Other Parts Discussed in Thread: TPS715 What is the over temperature shutdown point and tolerance for the LP2992 and TPS715?
The LP2992 mentions over temperature shutdown feature, however, it does not exactly mention shutdown point…
