    Voltage Regulator description and sizing

    I've got 4 suspect voltage regulators on the signal PCB AMC1117 F0810J. There is no -3.3 or -1.8, which do I choose when purchasing?

    Trying to get the VIZIO VP322 HDTV10A to have video.

    thanks,

    When no output voltage is specified, the regulator is adjustable.
    The regulator is working when the difference between output and adjust is 1.25V or so.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

      You choose the ADJ-ustable kind

      1117 is like generic pills, lots of companies make them ..LD1117, NXP1117, AP1117, NC1117, TLV1117, etc ... just check the chip package type and double check if the pins are arranged in the same order.

          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.

          diy - voltage injection possiblity with voltage and ampere regulator - possiblity ?
          by playit
          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...

          Help identifying voltage regulator on this concept 2 pm5 monitor pcb board?
          by artvandalai
          This Concept 2 rower pm5 monitor doesn't shut down. It keeps turning on and stays on after being turned off. I read on another forum by another user that replaced the same component to check the voltage regulator.
          The monitor should pull around 35mA when turned on and in shutdown it should drops to around 0.060mA. Any advice on finding the voltage regulator on this board to check if it needs to be replaced?

          Acer AL1916W - Two seconds to black - Voltage regulator problem?
          by Long AMD
          Hello all. Excellent forum you have here - it has already been a great help to me. I am posting the details of my situation before I go and start buying parts to see what suggestions the great minds here may have on diagnostics or otherwise.

          I have an Acer AL1916W monitor which has recently failed in the following way: the screen comes on at power on, but after a couple seconds the screen goes black. Using a flashlight, I can easily verify the LCD is fine but there is simply no backlight.

          The power supply board is of the type ILPI-025 Rev C (Date of manufacture was...

          Ram regulator misbehaving DDR3 VTT voltage Tps 51216
          by shakib200
          The ram regulator produces VTT voltage of 0.65V and the display comes. When we restart the laptop the VTT voltage becomes 0.75 and no display.[Used same ddr3l ram].
          Also, it becomes 1.35 V on the ram coil and all are okay but after restarting Voltage becomes 1.5V with no display.
