Stevie Wonder to Charlie Sheen -- I See Your $75K Cancer Donation ... & Raise You $25K!

Stevie Wonder is following Charlie Sheen's lead -- donating a TON of cash to help a little girl fight cancer ... and not that size matters, but Stevie's check was bigger.

Stevie was performing at the Nokia Theatre in L.A. last Saturday when he invited 10-year-old Jasmine Faulk on stage -- and presented her and her dad with a giant $100,000 check.

Stevie crowned the gesture by serenading Faulk with a rendition of "Isn't She Lovely" -- so if you don't feel like getting teary-eyed ... don't watch the video.

Oh yeah, Jasmine also grabbed the mic and said, "I love you Stevie!" before giving him a big adorable hug. Take that, feelings.

TMZ broke the story ... Charlie donated $75,000 to Jasmine's fund last week when he caught wind of her story through his stunt double Eddie Braun. Eddie had already donated $25,000 himself.
