Also changed all graphic to come to ART2 COME to get good pdf. Input graphics and changed name to LM1117 Added Application Note information shantha composed for vee. latest from Chris. Vee fixed the avo attributes from two-thirds to colwide as the title overprinted. Chris edited the electrical table and avo's and vee fixed the avo attributes and composed on 5/11/98 edit table updated and edited Chris 4/21/98 Chris to author in sgml DS100919 23900 19970801 Chris Russell LM1117 800mA௿υϩοϓΞ΢τɾϦχΞɾϨΪϡϨʔλ LM1117I 800mA௿υϩοϓΞ΢τɾϦχΞɾϨΪϡϨʔλ L1087 800mA ௿υϩοϓΞ΢τɾϨΪϡϨʔλ ཁ L1087 ͸ɺਖ਼ग़ྗͷ௿υϩοϓΞ΢τϨΪϡϨʔλͰ͢ɻ800mA · ͷεύΠΫిѹ ಛ௕ಛ௕ ಛ௕ಛ௕ ΞϓϦέʔγϣϯΞϓϦέʔγϣϯΞϓϦέʔγϣϯΞϓϦέʔγϣϯ ཰ͷϦχΞϨΪϡϨʔλ ˙ ఆిྲྀͷϨΪϡϨʔλ ˙ CPUݯ ੑೳϨΪϡϨʔλ ˙ 2.85Vɺ3.3Vɺ5.0V ͓ΑͼՄมग़ྗిѹ ˙௿ υ ϩοϓΞ΢τిѹ େग़ྗిྲྀ: 800mA ޢ ݶ ˙ ग़ྗਫ਼౓: ʶ2ˋ ϐϯ഑ஔਤϐϯ഑ஔਤ ϐϯ഑ஔਤϐϯ഑ஔਤ Package Maximum Temperature 125 ˆˆ ˆˆ Packaging Marking Transport Media NSC Drawing 3-lead SOT-223 L1087MPX-ADJ N08A Tape and Reel MA04A L1087MPX-2.85 N09A Tape and Reel L1087MPX-3.3 N10A Tape and Reel L1087MPX-5.0 N11A Tape and Reel 3-lead TO-252 L1087DTX-ADJ L1087DTX-ADJ Tape and Reel TD03B L1087DTX-2.85 L1087DTX-2.85 Tape and Reel L1087DTX-3.3 L1087DTX-3.3 Tape and Reel L1087DTX-5.0 L1087DTX-5.0 Tape and Reel SOT-223 Top View TO-252 Top View
