UNISONIC TECHNOLOGIES CO., LTD R200LD10 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 8 Copyright © 2011 Unisonic Technologies Co., Ltd QW-R101-022.E VOLTAGE REGULATOR „ DESCRIPTION The UTC R200LD10 shows a high current, high accuracy, low-dropout voltage. The features are: low 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 cu rrent values are important attributes). „ FEATURES * Built-in ON/OFF function, * Over current protection function, * ASO protection function * Overheat protection function Output low dropout voltage regulator „ ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free R200LD10L-TN4-R R200LD10G-TN4-R TO-252-4 Tape Reel R200LD10L-TN4-T R200LD10G-TN4-T TO-252-4 Tube R200LD10L-TN5-R R200LD10G-TN5-R TO-252-5 Tape Reel R200LD10L-TN5-T R200LD10G-TN5-T TO-252-5 Tube
