UNISONIC TECHNOLOGIES CO., LTD R1MX55 LINEAR INTEGRATED CIRCUIT 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 Lead Free Halogen Free R1MX55L-xx-AB5-R R1MX55G-xx-AB5-R R1MX55L-xx-SH2-R R1MX55G-xx-SH2-R R1MX55L-xx-SH2-T R1MX55G-xx-SH2-T R1MX55L-xx-AB5-R (1)Packing Type Package Packing SOT-89-5 HSOP-8 HSOP-8 Tape Reel Tape Reel Tube (1) R: Tape Reel, T: Tube (2)Package Type (2) AB5: SOT-89-5, SH2: HSOP-8 (3)Output Voltage Code (3) xx: refer to Marking Information (4)Lead Free (4) G: Halogen Free, L: Lead Free www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 10 QW-R101-023.F R1MX55 LINEAR INTEGRATED CIRCUIT MARKING INFORMATION PACKAGE VOLTAGE CODE MARKING 15: 1.5V SOT-89-5 18: 1.8V 25: 2.5V 33: 3.3V UTC R1MX55 G 50: 5.0V HSOP-8 AD: ADJ Voltage Code Date Code L:Lead Free G:Halogen Free Lot Code PIN CONFIGURATION VOUT 1 8 VIN NC 2 7 GND 3 6 NC 4 5 EN GND NC NC/ADJ FOR HSOP-8 PIN DESCRIPTIONS FOR ADJUSTABLE VERSION PIN NO.
