Part Number: LP2980-ADJ Hi TI support, engineering and technical team,
To whom it may concern, we need your help in an urgent matter. We have these two-part numbers and datasheets from supplier Digi-key and distributor, LP2980IM5-ADJ RE suffix /NOPB…
Part Number: LP2980-ADJ Tool/software: Hello,
We have been using the LP2980IM5-ADJ/NOPB in one of our PCBs for some time. Initially, we experienced some issues with output noise, which we resolved by adding a 6.8 pF feed-forward capacitor, as recommended…
Part Number: LP2980-ADJ According to 9.1.1 Device Nomenclature in the datasheet, the version of the New chip should be LP2980Axxxz-ADJ/M3, but the package information says LP2980IM5-ADJ/NOM3. Which is the correct information?
Part Number: LP2980-ADJ Expert,
The customer actually measured the ADJ voltage value of 31 boards and found that nearly half of the ADJ voltage values of this LP2980IM5X-ADJ/NOPB are close to or lower than the Vref lower limit.
Please refer to the…
Part Number: LP2980-ADJ Hello,
On LP2980 I see the recommendation of 51.1k on the product datasheet. I need to adjust that value as high as 56.2k for my application needs. I know I can create an offset error in Vout but was interested if TI can comment…
Part Number: LP2980-ADJ Other Parts Discussed in Thread: LM317 , LM334 Can the LP2980-ADJ be used as a current source set to 1.5ma by leaving the ADJ open and connecting it to the output pin with a 820 resistor.
Device would charge a battery. Regulator…
Hi,
1. Note that the pass element of the LP2980-ADJ is a Vertically Integrated PNP (VIP) BJT, not a FET. BJTs offer better performance in applications that require high voltage and low noise, like telecommunications equipment. This type of pass device…
