UNISONIC TECHNOLOGIES CO., LTD R1MX55 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). LINEAR INTEGRATED CIRCUIT FEATURES * Built-in ON/OFF function, * Over current protection function, * Over heat protection function * Adjustable DC output voltage * 30mA / 2.44V Output low dropout voltage regulator Lead-free: R1MX55L Halogen-free: R1MX55G ORDERING INFORMATION Normal R1MX55-AB5-R Ordering Number Lead Free R1MX55L-AB5-R Halogen Free R1MX55G-AB5-R Package SOT-89-5 Packing Tape Reel R1MX55L-AB5-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel (2) AB5: SOT-89-5 (3) G: Halogen Free, L: Lead Free, Blank: Pb/Sn www.unisonic.com.tw Copyright © 2008 Unisonic Technologies Co., Ltd 1 of 8 QW-R101-023.B R1MX55 PIN DESCRIPTIONS PIN NO.
