Part Number: LP3985 Hi,
I am debugging a new design that uses the LP3985-2.5 to power a FPGA. The same FPGA also has banks running on 3.3V. I have a series 0 ohm resistor between the regulator and FPGA so I can disconnect the FPGA load leaving only the…
Part Number: LP3985 Other Parts Discussed in Thread: TLV713 , At a review of my design a collegue complained, that with the minimum input voltage of 4,4V the 5V-LDO will not work, as the datasheet sais:
'7.4.1 Operation with VOUT(TARGET) 0.3 V ≤ VIN…
Part Number: LP3985 Hi,
Recently my customer tested the LP3985 with Vin > abs max, let's say 7V. He noticed that the device will shut down. If 7V is reduced to 5V, the device works again. Is this part of the protection and is a confirmed feature…
Part Number: LP3985 Hi,
LP3985-2.5 is used to drive LED with 5mA. What would happen if input is 7V which is slightly exceed the absolute voltage of 6.5V. Would it failed? If not, what is the maximum voltage it can withstand without damaging the device…
Other Parts Discussed in Thread: LP3985 Hello,
The LP3985 datasheet refers to two functional modes in section 7.4:
7.4.1 Operation with VOUT(TARGET) + 0.3 V ≤ VIN ≤ 6 V The device operates if the input voltage is equal to, or exceeds, VOUT(TARGET) + 0…
Other Parts Discussed in Thread: LM4132 , LP3990 , LP3985 'Load Regulation' is specified from 1mA to 150mA for these parts. Can the regulator run and maintain output specifications below 1mA? Presumably they'll run smaller loads but will they suffer…
Hello Stewart,
Where is the 100uF capacitor on the input to the LP3985 located? How far away is it? Also what type of capacitor is it because it looks like an electrolytic. First thought would be to replace the input cap C107 with a 1uF ceramic.
The…
Other Parts Discussed in Thread: LP3990 , LP3985 Hi all!
Because "asktexas" incomprehensibly doesn't let ask anything :
have I 2 questions:
1. LP3985 has Cbyp 10nF at PIN4, LP3990 PIN4 is specified as UNCONNECTED, must the Cbyp be removed? …
Other Parts Discussed in Thread: DM3725 , LP55231 , DM385 Hello. After search for DM3725 I found some comments about which components are used by another developers. My goal to make a sound voice decisions and it seems that this what I want to use. Please…
