    Help...Replacement of LDO voltage regulator

    I sure could use some help with replacement of a LDO voltage regulator...any help would be appreciated.
    I have a camera flash with twin heads that in the late hours of the evening while shooting macro photos of insects...I put a couple batteries in backwards and it blew a 47uf capacitor, (replaced already), it messed up a 6 pin 2 position switch (replaced already) and also a 7536-1 LDO voltage regulator, 100mA, 3.6v OUTPUT, ±3%, SOT-89.


    Data sheet here-- HT7536-1 LDO voltage regulator, 100mA, 3.6v OUTPUT, ±3%, SOT-89

    Input power source on this unit is 4 pcs. - AA, 1.2v, 2500mAh rechargeable batteries.


    What would be any equal replacement for this 7536-1 (EOL) component?


    I have searched and looked in many places but my limited knowledge of electronics impedes me from finding a suitable replacement.

      I don't find any available in the USA though...???

      Is that a trustworthy site to order from and ship to USA??

      Also I am looking for a suitable replacement since the 7536-1 is EOL...

        Maybe this? Diodes Incorperated AP7383-36Y-13

          Thanks..it is close to the original....But I have a question, please.

          This AP7383-36Y-13 is 150mA and the original was 100mA....
          Some other variables are not the same also...

          Should this be done or maybe it will be too many amps or other variables will be too high for the circuit???

          Remember i am a beginner at this so that is why all the questions.

          I don't wish to burn anything up or ruin the flash unit beyond repair???

            150ma is the maximum it can provide, so it's better than the original

              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...

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              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...
