UNISONIC TECHNOLOGIES CO., LTD 78RXX LINEAR INTEGRATED CIRCUIT LOW DROPOUT VOLTAGE REGULATOR 1 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). TO-220F-4 FEATURES * 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 1 1 TO-252-5 ORDERING INFORMATION 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.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd Package Packing TO-220B TO-220F-4 TO-252-5 Tube Tube Tape Reel 1 of 12 QW-R102-035.E 78RXX MARKING INFORMATION PACKAGE LINEAR INTEGRATED CIRCUIT VOLTAGE CODE TO-220F-4 33: 05: 09: 12: 3.3V 5.0V 9.0V 12V TO-220B/ TO-252-5 33: 05: 09: 12: 00: 3.3V 5.0V 9.0V 12V ADJ MARKING 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 signal input pin Adjustable input pin ( FOR TO-220B/TO-252-5 ) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 12 QW-R102-035.E 78RXX LINEAR INTEGRATED CIRCUIT BLOCK DIAGRAM Fixed Output Voltage Versions Overvoltage Protection Bandgap Reference VIN 1 + Thermal Shutdown Q1 SOA Protection R1 2 VOUT Short-Circuit Protection High/Low - Output ON/OFF + R2 1.4V 3 GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 4 VDIS 3 of 12 QW-R102-035.E 78RXX LINEAR INTEGRATED CIRCUIT BLOCK DIAGRAM Adjustable Output Voltage Versions Overvoltage Protection Bandgap Reference VIN 1 + Thermal Shutdown Q1 SOA Protection 2 VOUT Short-Circuit Protection High/Low - Output ON/OFF + 1.4V 3 5 GND ADJ UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 4 VDIS 4 of 12 QW-R102-035.E 78RXX LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS (Operating temperature range applies unless otherwise specified. ) PARAMETER SYMBOL VIN VDIS IOUT RATINGS UNITS 35 V 35 V 1.0 A TO-220B/TO-220F-4 1.5 W Power Dissipation PD TO-252-5 1 W Junction Temperature TJ +150 °C Operating Temperature TOPR -40 ~ +85 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
