got a sot23 marked "5JRA".
i think it's a regulator - anybody know it?

Re: component help marked "5JRA"
Can you post a clear picture of it . -
Re: component help marked "5JRA"
no, the device is temporarily re-assembled.
it's just a 3pin sot-23 package with power going in, ground and power coming out.
i just dont know the voltage or the current limit.Comment

R3131N45EA is the best i can find. http://chip.tomsk.ru/chip/chipdoc.ns...4501&count=500 https://datasheetspdf.com/pdf/122838...H/R3131N45EA/1Comment

Re: component help marked "5JRA"
where are the product markings in the datasheet??Comment

Re: component help marked "5JRA"
just the code in bold - no room for any logo on a sot23
i may be able to get another later and just meter it - it's in a high-end flashlight between the battery and mcu.Comment

Re: component help marked "5JRA"
All the google images for that microne part have the logo ,so maybe it isn`t that after all.Comment

Re: component help marked "5JRA"
doesnt matter now,
i know the important bit - output is 2v7

Re: component help marked "5JRA"
I also find oddball chinese (fab) SMT marking codes searching at Ali, as a last resort.Comment

Re: component help marked "5JRA"
Here are some without the logo
Looks like some of the markings are:
1.5V = 65E9
1.8V = 65K5
3.0V = 65Z5
3.3V = 662K
This datasheet for the XC6202 series has a voltage chart that might helpAttached FilesLast edited by R_J; 01-16-2021, 04:58 PM.Comment

Hello
Anybody came across this tiny sot23-6 PWM and knows where to find data sheet or yet better pin-pin compatible chop?... -
Hello everyone,
I want to find a replacement for uP0109 8pins, and i found this parts:
uP0109 is "2A Ultra Low Dropout Linear Regulator"
RT9199 is "Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator"
FP6137C is "2A BUS TERMINATION REGULATOR"
can replace uP0109 by RT9199 or FP6137C ? -
Hello,
Device: PocketBook InkPad 3
Mainboard: XRZ_E091_PB740-VTTOA-V1.1 / 2017-10-12
I'm replacing the broken microUSB connector on this e-reader, and during inspection after desoldering, I noticed a loose black SMD component marked "CT". One of them was torn off along with the pad, while the other one (marked in the photo) is still in place.
I would appreciate help identifying this component.
Measuring the loose component with a multimeter gives 5.84 MΩ in both directions, while the one still on the board shows no measurable... -
hello ,for diy voltage injector for short killer/finder -- is it possible to use something like this - LM317 DC Linear Regulator, DC-DC 4.5~40V Turn 1.2~37V, Step Down Power Module, Adjustable
and ampere controller along (to make it zero amps ) with some addons(transistors diodes etc.) for it -- and use some 5v adaptor or 3.3v volt rail of my smps power supply as input and finally get 1v and zero amps for injecting voltage to find out short circuit component ? ..
for source input -- can we use 3.3 -4 volt 18550 battery ?( i have some of those ) and then adding ampere regulator... -
3+1 Voltage Regulator for IMVP-7/VR12 CPUs
Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.
Based on Intersil's Robust Ripple Regulator...11-05-2024, 03:24 PM
