Ladies and Gentlemen:

We have acted as special U.S. counsel for Medtronic, Inc., a Minnesota corporation (the “Company”) in connection with the offer and sale of $150,000,000 aggregate principal amount of its 4.625% Senior Notes due 2045 (the “Notes”), pursuant to an underwriting agreement dated as of March 21, 2017, among the Company, the Guarantors (as defined below) and Citigroup Global Markets Inc., Goldman, Sachs & Co., Morgan Stanley & Co. LLC, as representatives of the several underwriters (the “Underwriting Agreement”). The Notes will be fully and unconditionally guaranteed (the “Guarantees”) by Medtronic Global Holdings S.C.A., an entity organized under the laws of Luxembourg (“Medtronic Luxco”) and Medtronic Public Limited Company, a company organized under the laws of Ireland (“Medtronic plc,” and together with Medtronic Luxco, the “Guarantors”). The Notes will be issued pursuant to the indenture, dated as of December 10, 2014 (the “Base Indenture”), between the Company and Wells Fargo Bank, N.A., as trustee (the “Trustee”), as supplemented by the first supplemental indenture, dated as of December 10, 2014, between the Company and the Trustee (the “First Supplemental Indenture”), the second supplemental indenture, dated as of January 26, 2015, between Medtronic plc and the Trustee (the “Second Supplemental Indenture”) and the third supplemental indenture, dated as of January 26, 2015, between Medtronic Luxco and the Trustee (the “Third Supplemental Indenture,” and together with the Base Indenture, the First Supplemental Indenture and the Second Supplemental Indenture, the “Indenture”).

The Company and the Guarantors have filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-215895) under the Securities Act of 1933, as amended (the “Securities Act”), on February 6, 2017 (the “Registration Statement”), including the prospectus dated as of February 3, 2017 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement dated as of March 21, 2017 (the “Preliminary Prospectus Supplement”) relating to the Notes, and a prospectus supplement dated as of March 21, 2017 (the “Prospectus Supplement”) relating to the Notes.

We have examined and relied upon signed copies of the Registration Statement, the Base Prospectus, the Preliminary Prospectus Supplement, the Prospectus Supplement, the

Underwriting Agreement, the Indenture, the Notes and the Guarantees. For purposes of this opinion, we have also examined and relied without investigation upon the accuracy of (i) the opinion letter of A&L Goodbody, Irish counsel for the Company, dated the date hereof and filed as Exhibit 5.2 to Medtronic plc’s Current Report on Form 8-K to be filed on the date hereof (the “Form 8-K”); (ii) the opinion letter of Allen & Overy, société en comandite simple (inscrite au barreau de Luxembourg), special Luxembourg counsel for Medtronic Luxco dated the date hereof and filed as Exhibit 5.3 to the Form 8-K; and (iii) the opinion letter of Thomas L. Osteraas, Principal Legal Counsel, Corporate & Securities of Medtronic, Inc., dated the date hereof and filed as Exhibit 5.4 to the Form 8-K. We have relied as to certain matters on information obtained from public officials and officers of the Company, Medtronic Luxco and Medtronic plc.

In our examination of the documents referred to above, we have assumed the genuineness of all signatures, the legal capacity of all individual signatories, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, and the authenticity of such original documents. Insofar as the opinions relate to factual matters, we have assumed, without independent investigation, that representations of officers and directors of the Company and the Guarantors and documents furnished to us by the Company and Guarantors are true and correct.

In rendering the opinions set forth below, we have assumed that (i) the Trustee has the power, corporate or other, to enter into and perform its obligations under the Indenture; (ii) the Indenture, the Notes and the Guarantees have been duly authorized, executed and delivered by all parties thereto; and (iii) the Indenture is a valid and binding obligation of the Trustee. We have also assumed that the Board of Directors (or comparable body) of the Company and the Board of Directors (or comparable body) of each Guarantor (or any person acting pursuant to authority properly delegated to such person by the Board of Directors (or comparable body) of the Company or the Board of Directors (or comparable body) of each Guarantor) have not taken any action to rescind or otherwise reduce their prior authorization of the issuance of the Notes.

Our opinions below are qualified to the extent that they may be subject to or affected by (i) applicable bankruptcy, insolvency, reorganization, moratorium, usury, fraudulent conveyance or similar laws relating to or affecting the rights or remedies of creditors generally; (ii) statutory or decisional law concerning recourse by creditors to security in the absence of notice or hearing; (iii) duties and standards imposed on creditors and parties to contracts, including, without limitation, requirements of materiality, good faith, reasonableness and fair dealing; and (iv) general equitable principles. Furthermore, we express no opinion as to the availability of any equitable or specific remedy upon any breach of the Indenture, the Notes, or the Guarantees, or to the successful assertion of any equitable defenses, inasmuch as the availability of such remedies or the success of any equitable defenses may be subject to the discretion of a court. We express no opinion herein as to the laws of any jurisdiction other than the state laws of the State of New York. We have not acted as counsel for the Company with respect to matters of Irish law, Luxembourg law or other applicable foreign law.
