UNISONIC TECHNOLOGIES CO., LTD 78RXXX LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 9 Copyright © 2023 Unisonic Technologies Co., Ltd QW-R102-035.V LOW DROPOUT VOLTAGE REGULATOR DESCRIPTION As the UTC linear integrated LDO, the UTC 78RXXX shows a high current, high accuracy, and specially low-dropout voltage. The features are: maximum 500mV dr opout 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). FEATURES * IOUT=1A ; VOUT=1.5V, 1.8V, 3.3V, 5V, 6V, 9V,10V, 12V, 15V (Typ.) With ADJ version * Built in ON/OFF Control Terminal * Built in Over Current Protection, Over Heat Protection Function ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free 78RXXXL-AA3-R 78RXXXG-AA3-R SOT-223 Tape Reel 78RXXXL-TA3-T 78RXXXG-TA3-T TO-220 Tube 78RXXXL-TB5-T 78RXXXG-TB5-T TO-220B Tube 78RXXXL-TF3-T 78RXXXG-TF3-T TO-220F Tube 78RXXXL-TF4-T 78RXXXG-TF4-T TO-220F-4 Tube 78RXXXL-TN3-R 78RXXXG-TN3-R TO-252 Tape Reel 78RXXXL-TN5-R 78RXXXG-TN5-R TO-252-5 Tape Reel Note: xxx: output voltage, re fer to Marking Information
