Part Number: LP2985-N Other Parts Discussed in Thread: LP2985 , Hi,
i have a question with regards to LP2985 recommended design guideline which relates to capacitors to use on my design. I'm now looking into downsizing the passive ceramic capacitor that…
Hi Alejandro,
These devices are in the same package, have the same pinout, and have extremely similar specs. They are, however, categorized under different generic part numbers. The reasoning for this is that the original device was acquired by TI with…
Part Number: LP2985-N Hi,
In datasheet, 1.6V is the minimum to enable and 0.15V is the maximum to disable. Questions:
What is the accuracy for this threshold value?
What happen to Vout if Ven falls in between 0.15V and 1.6V?
Can I have the Ven vs Vout…
Part Number: LP2985-N Other Parts Discussed in Thread: ADS1299 , LP2985 Hello,
I have designed and manufactured the following circuit:

There I use a LP2985 LDO to power my ADS1299 with 3.3V, the input voltage of the LDS is 5V. However…
Part Number: LP2985-N We are trying to use the 3.3 V LDO regulator to step down a 9 V battery. It is working correctly and it says on the data sheet that it can handle voltages up to 16 V, but I am concerned about it being able to handle the power dissipation…
Part Number: LP2985-N I am using an LP2985IM5-5.0 with the recommended circuit from the data sheet. I have 10V input, 5V out, about 10mA load. I have seen 2 failures where the output voltage is about 6.5V on both failures. There is no oscillation on the…
Part Number: LP2985-N Have used the LP2985IM5X-5.0/NOPB in a circuit for many years without any problems. We have recently had instruments where this component is blowing. It looks like the output has blown, but looking at the datasheet there should be…
Part Number: LP2985-N I would like to ask you to review the attached schematic, regading the output capacitor selection and stability. Recommend better type if I'm wrong. I need this becouse I'm facing with the following problem: At the EMC laboratory…
HI Andrew,
I would recommend testing with a pull-down at ENABLE to see if it helps.
If you are using LP2985-N then it does not have an output pull-down, the one I showed was the newer version LP2985 (non-N): https://www.ti.com/lit/ds/symlink/lp2985.pd…

Here is the part of the 3.6V regulate circuit I intended to make. However, with 3.3v input, it does not give me an 3.6 output. Is there anything wrong with the design? what should I change?
