1 UNISONIC TECHNOLOGIES CO., LTD 78RXXX LOW DROPOUT VOLTAGE REGULATOR DESCRIPTION TO-220B 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 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 * I OUT =A ; V OUT =.5V,.8V, 3.3V, 5V, 6V, 9V, 2V, 5V (Typ.) * With ADJ version * Built in ON/OFF Control Terminal * Built in Over Current, Over Heat Function TO TO-252 ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing 78RXXXL-TB5-T 78RXXXG-TB5-T TO-220B 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 Tape Reel Note: xx: output voltage, refer to Marking Information of 9 Copyright 208 Unisonic Technologies Co., Ltd
