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 1.8V 2.5V 2.85V 3.3V 5V SOT-223 LLP 800mA 0.2 ( ) 0.4 ( ) LM1117 LM1117I Active Terminator for SCSI-2 Bus 2.85V SCSI-2 DC/DC mA Fixed Output Regulator National Semiconductor Corporation DS JP 1 Printed in Japan NSJ 2/2002
