    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
