1 UNISONIC TECHNOLOGIES CO., LTD LOW DROP POSITIE OLTAGE REGULATORS DESCRIPTION The UTC LR1118 is a low drop voltage regulator able to provide up to 1A of output current, available also for adjustable version ( REF =1.24). Output consists of PNP power transistor. So that dropout voltage can be extremely low. FEATURES * 2.85 device are suitable for SCSI-2 active termination * Output current up to 1A * Adjustable version available.( REF =1.24) * Internal current and thermal limit ORDERING INFORMATION Ordering Number 1 Package Lead Free Halogen Free Pin Assignment - LR1118G-xx-AA3-1-2 SOT-223 A: GOI LR1118L-xx-TA3-1-2 LR1118G-xx-TA3-1-2 TO-220 B: OGI LR1118L-xx-TN3-1-2 LR1118G-xx-TN3-1-2 TO-252 C: GIO LR1118L-xx-TQ2-1-2 LR1118G-xx-TQ2-1-2 TO-263 D: IGO LR1118L-xx-TQ3-1-2 LR1118G-xx-TQ3-1-2 TO LR1118G-xx-S SOP-8 GOOIxOOx Note: 1.
