LM2940G-XX-TN3-R

UNISONIC TECHNOLOGIES CO., LTD LM2940 1A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR DESCRIPTION The UTC LM2940 is a low dropout regulator designed to provide output current up to 1A with a typically 500mV dropout Voltage and a maximum of 1V. It is capable of reducing the ground current when the differential between the input voltage and the output voltage outrun 3V. UTC LM2940 offers low quiescent current (typically 30mA at 1A and an input-output differential of 5V). Higher quiescent currents only exist when the regulator is in the dropout mode (VIN-VOUT≤3V). LINEAR INTEGRATED CIRCUIT 1 FEATURES * 500mV Typically Dropout at 1A * Output Current in Excess of 1A * Low Quiescent Current * Reversed-Battery Protection * Current Limit and Thermal Shutdown. * Mirror Image Insertion Protection ORDERING INFORMATION Ordering Number Lead Free Halogen Free LM2940L-xx-AA3-R LM2940G-xx-AA3-R LM2940L-xx-TA3-T LM2940G-xx-TA3-T LM2940L-xx-TN3-R LM2940G-xx-TN3-R LM2940L-xx-TN3-T LM2940G-xx-TN3-T LM2940L-xx-TQ2-R LM2940G-xx-TQ2-R LM2940L-xx-TQ2-T LM2940G-xx-TQ2-T LM2940L-xx-TQ3-R LM2940G-xx-TQ3-R LM2940L-xx-TQ3-T LM2940G-xx-TQ3-T Note: 1.xx: Output Voltage, refer to Marking Information. 2.Pin Assignment: I: VIN G: GND O:VOUT Package SOT-223 TO-220 TO-252 TO-252 TO-263 TO-263 TO-263-3 TO-263-3 Pin Assignment 1 2 3 I G O I G O I G O I G O I G O I G O I G O I G O Packing Tape Reel Tube Tape Reel Tube Tape Reel Tube Tape Reel Tube www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd 1 of 11 QW-R102-016.J LM2940 MARKING INFORMATION PACKAGE VOLTAGE CODE LINEAR INTEGRATED CIRCUIT MARKING SOT-223 TO-220 TO-252 TO-263 TO-263-3 50 : 5V 60 : 6V 80 : 8V 90 : 9V 10 :10V 12 :12V 15 :15V Voltage Code Lot Code UTC LM2940 L: Lead Free G: Halogen Free Date Code 1 2 3 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 11 QW-R102-016.J LM2940 ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL VIN PD TJ LINEAR INTEGRATED CIRCUIT RATINGS UNIT Input Voltage 26 V Power Dissipation Internally limited Junction Temperature +150 °C Ambient Operating TO-220/TO-263-3/TO-263 -40 ~ +125 °C TOPR Temperature -40 ~ +85 °C SOT-223 Storage Temperature TSTG -65 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
