UNISONIC TECHNOLOGIES CO., LTD LR9XXYY Advance CMOS IC 300mA SMALL DUAL LDO REGULATOR DESCRIPTION 6 The UTC LR9XXYY Series are a low dropout regulator with high output voltage accuracy, low quiescent current, low dropout, and high ripple rejection. This regulator is based on a CMOS process. Each of these regulator ICs contains dual LDO regulator, both of them includes a voltage reference, an error amplifier, resistors for setting Output Voltage, a current limit circuit, and a chip enable circuit. The UTC LR9XXYY Series exhibit ultra excellent line transient response and load transient response, thus they are very suitable for the power supply for hand-held communication equipment. 5 4 1 2 3 SOT-23-6 (JDEDE TO-236) FEATURES * Supply Current: TYP. 50μA×2 (VR1&VR2) * Standby Current: TYP. 0.1μA×2 (VR1&VR2) * Input Voltage Range: 1.4V~5.25V * Output Voltage Range: 0.8V~3.7V (0.1V steps) (For details, please refer to MARK SPECIFICATION TABLE) * Output Voltage Accuracy: ±1.0% (VSET>2.0V, TOPT=25°C) * Temperature-Drift Coefficient of Output Voltage: TYP. ±80ppm/°C * Dropout Voltage: TYP. 0.25V (IOUT=300mA, VSET=2.5V) * Ripple Rejection: TYP. 75dB (f=1kHz) * Line Regulation: TYP. 0.02%/V * Built-in Fold Back Protection Circuit: TYP. 60mA (Current at short mode) * Ceramic capacitors are recommended to be used with this IC: 1.0μF or more RDERING INFORMATION Note: Ordering Number LR9XXYYBG-AE6-R XXYY: Output Voltage, refer to Marking Information.
