78RXX

UNISONIC TECHNOLOGIES CO., LTD 78RXX LOW DROPOUT VOLTAGE REGULATOR 1 LINEAR INTEGRATED CIRCUIT „ DESCRIPTION TO-220B As the UTC linear integrated LDO, the UTC 78RXX shows a high current, high accuracy, and specially low-dropout voltage. The features are: maximum 500mV dropout voltage, very low ground current. Cause the series have been designed for high current loads, so they are also used in lower current, extremely low dropout-critical systems (in which their tiny dropout voltage and ground current values are important attributes). 1 TO-220F-4 „ FEATURES 1 * IOUT=1A ; VOUT=3.3V,5V,9V,12V (typ) * With ADJ version * Internal overcurrent protection, internal thermal shutdown * Internal overvoltage protection, internal short-circuit protection * Output disable function TO-252-5 „ ORDERING INFORMATION Package TO-220B TO-220F-4 TO-252-5 Packing Tube Tube Tape Reel Ordering Number Lead Free Halogen Free 78RXXL-TB5-T 78RXXG-TB5-T 78RXXL-TF4-T 78RXXG-TF4-T 78RXXL-TN5-R 78RXXG-TN5-R Note: xx: output voltage, refer to Marking Information www.DataSheet4U.com www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 12 QW-R102-035.E 78RXX „ MARKING INFORMATION PACKAGE VOLTAGE CODE 33: 05: 09: 12: 33: 05: 09: 12: 00: 3.3V 5.0V 9.0V 12V 3.3V 5.0V 9.0V 12V ADJ LINEAR INTEGRATED CIRCUIT MARKING TO-220F-4 TO-220B/ TO-252-5 „ PIN DESCRIPTIONS PIN NO. 1 2 3 4 5 PIN NAME VIN VOUT GND VDIS ADJ PIN FUNCTION Input voltage pin Output voltage pin GND Disable si...
