UNISONIC TECHNOLOGIES CO., LTD LR6401 CMOS IC DUAL CHANNEL LDO REGULATORS WITH ENABLE FUNCTION 6 5 4 1 3 DESCRIPTION SOT-26 The UTC LR6401 is a low noise and high accuracy LDO voltage regulator which has enable soft start function. Designers can reduce power consumption more easily by applying EN function that can turn off the output of each device and control the in rush current through the soft the start function. The UTC LR6401 comes with low design cost and outstanding output stability and its compatibility of working with low ESR ceramic capacitors is undoubted. Besides, and this level of stability is ensured by the perfect transient response and PSRR derived from a large frequency range. 2 1 DFN-6 (1.8×2.0) FEATURES * VD=150mV @100mA (Typ.), VOUT ≥2.8V * Range of Operating Voltage:2.5V ~ 6.0V * Range of Output Voltage Range:1.2V ~ 4.0V * Range of Output Current:300mA / Channel * Low Power Consumption:30μA (Typ.) for Each Channel * Standby Current:0.1μA (Typ.) * Accurate：±2% * High PSRR: 65 dB * Each Channel Output Current Limit Protection:450mA * With Short Circuit Protection * Output ON/OFF Control Function ORDERING INFORMATION Ordering Number LR6401xG-AG6-R LR6401xG-K06-1820-R Note: x: Output Voltage, refer to Marking Information. www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd Package SOT-26 DFN-6(1.8×2.0) Packing Tape Reel Tape Reel 1 of 8 QW-R502-332.O LR6401 CMOS IC MARKING INFORMATION PACKAGE SOT-26 DFN-6(1.8×2.0) VOLTAGE VOLTAGE CODE 1.8V + 3.3V 1.8V + 2.8V 2.5V + 3.3V 2.8V + 3.3V 2.8V + 1.8V 3.3V + 2.8V 2.85V + 2.85V 1.2V + 2.8V 1.5V + 2.8V 1.2V + 1.8V A B C D E F H M N P PIN CONFIGURATION PIN DESCRIPTION PIN NO.
