UNISONIC TECHNOLOGIES CO., LTD UCV676/A LINEAR INTEGRATED CIRCUIT 400mA LOW-DROP VOLTAGE REGULATOR  DESCRIPTION The UTC UCV676/A is a low dropout voltage regulator with a 400mA output current used in harsh automotive environments. It can be used in wide input voltage and operating temperature ranges. It has a high peak input voltage tolerance and reverse input voltage protection. Built-in heat protection circuit, current limiting circuit and inhibit control circuit. The UTC UCV676/A family is available in TO-263-5 and TO-252-4 surface mount packages. The output is stable over a wide output capacitance and ESR range.  FEATURES * 2.5V and 1.8V ±4% Output Voltage * 3.3V, 5.0V, and Adjustable Voltage Version (from 2.5V~20V) ±4% or ±2% Output Voltage * 400mA Output Current * 500mV (max) Dropout Voltage (5.0V Output) * Inhibit control input * Very Low Current Consumption * Fault Protection － +45V Peak Transient Voltage － Overcurrent － Overheat  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UCV676L-TQ5-R UCV676G-TQ5-R UCV676L-TQ5-T UCV676G-TQ5-T UCV676AL-TQ5-R UCV676AG-TQ5-R UCV676AL-TQ5-T UCV676AG-TQ5-T UCV676L-TN4-R UCV676G-TN4-R UCV676L-TN4-T UCV676G-TN4-T UCV676AL-TN4-R UCV676AG-TN4-R UCV676AL-TN4-T UCV676AG-TN4-T 1 1 Package TO-263-5 TO-263-5 TO-263-5 TO-263-5 TO-252-4 TO-252-4 TO-252-4 TO-252-4 TO-263-5 TO-252-4 Packing Tape Reel Tube Tape Reel Tube Tape Reel Tube Tape Reel Tube UCV676L-TN4-R (1)Packing Type (2)Package Type (3)Lead Plating (1) T: Tube, R: Tape Reel (2) TN4: TO-252-4, TQ5: TO-263-5 (3) L: Lead Free, G: Halogen Free www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 9 QW-R102-051.
