This CMOS process also allows the device to oper ate under extremely low dropout conditions. The UTC L1119 allows to operate from a 2.5V~7.0V input supply. Wide range of preset output vo ltage options are available and respond very fast to step changes in load which makes them suitable for low voltage microprocessor applications. „ FEATURES * Low ground current * Load regulation of 0.04% * Output current of 1.5A DC is guaranteed * Accurate output voltage.(± 1.5%) * Extremely low output capacitor requirements * Over temperature/ Over current protection SOT-89 SOT-223 TO-252 *Pb-free plating product number: L1119L-xx „ ORDERING INFORMATION Order Number Pin Assignment Normal Lead Free Plating Package 1 2 3 Packing L1119-xx-AA3-A-R L1119L-xx-AA3-A-R SOT-223 G O I Tape Reel L1119-xx-AA3-C-R L1119L-xx-AA3-C-R SOT-223 G I O Tape Reel L1119-xx-AB3-A-R L1119L-xx-AB3-A-R SOT-89 G O I Tape Reel L1119-xx-AB3-B-R L1119L-xx-AB3-B-R SOT-89 O G I Tape Reel L1119-xx-AB3-C-R L1119L-xx-AB3-C-R SOT-89 G I O Tape Reel L1119-xx-AB3-D-R L1119L-xx-AB3-D-R SOT-89 I G O Tape Reel L1119-xx-TN3-D-R L1119L-xx- TN3-D-R TO-252 I G O Tape Reel L1119-xx-TN3-D-T L1119L-xx-TN3- D-T TO-252 I G O Tube Note: Pin assignment: I: VIN O : VOUT G:GND L1119L-xx-AA3-A-R (1)Packing Type (3)Package Type (4)Output Voltage Code (5)Lead Plating (2)Pin Assignment (1) R: Tape Reel, T: Tube (2) refer to Pin Assignment (3) AA3: SOT-223, AB3: SOT-89, TN3: TO-252 (4) xx: refer to Marking Information (5) L: Lead Free Plating , Blank: Pb/Sn

Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the drop-out voltage is not hing but the input to output differential, since the minimum input voltage is 2.5V.
