UNISONIC TECHNOLOGIES CO., LTD R1MX55 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 10 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R101-023.F VOLTAGE REGULATOR „ DESCRIPTION As the UTC linear intergrated LDO, the R1MX55 shows a high current, high accuracy, low-dropout voltage. The feature 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 current values are important attributes). The R1MX55 is stable with ceramic capacitors. It requires a 1μF or greater capacitor for stability. „ FEATURES * Available and fixed output versions 1.5V, 1.8V, 2.5V, 3.3V, 5V * Built-in ON/OFF function * Over current protection function * Over heat protection function * Adjustable DC output voltage „ ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free R1MX55L-xx-AB5-R R1MX55G-xx-AB5-R SOT-89-5 Tape Reel R1MX55L-xx-SH2-R R1MX55G-xx-SH2-R HSOP-8 Tape Reel R1MX55L-xx-SH2-T R1MX55G-xx-SH2-T HSOP-8 Tube (1) R: Tape Reel, T: Tube (2) AB5: SOT-89-5, SH2: HSOP-8 (3) xx: refer to Marking Information (4) G: Halogen Free, L: Lead Free R1MX55L-xx-AB5-R (1)Packing Type (2)Package Type (3)Output Voltage Code (4)Lead Free
