UNISONIC TECHNOLOGIES CO., LTD LR8XXYY Preliminary CMOS IC 150mA DUAL LDO REGULATOR 6 DESCRIPTION 4 1 The UTC LR8XXYY 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 LR8XXYY 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 2 3 SOT-23-6 (JDEDE TO-236) 1 DFN-6(1.6x1.6) FEATURES * Supply Current: TYP. 40μA (VR1, VR2) * Standby Mode: TYP. 0.1μA (VR1, VR2) * Low Dropout Voltage: TYP. 0.22V(IOUT=150mA, VOUT=2.8V) * High Ripple Rejection: TYP. 70dB (f=1kHz), TYP. 65dB (f=10kHz) * High Output Voltage Accuracy: ±1.0% * Low Temperature-Drift Coefficient of Output Voltage: TYP. ±80ppm/°C * Excellent Line Regulation: TYP. 0.02%/V * Built-in Fold Back Protection Circuit TYP. 40mA (Current at short mode) * Ceramic capacitors are recommended to be used with this IC 0.22μF or more RDERING INFORMATION Note: Ordering Number LR8XXYYBG-AE6-R LR8XXYYBG-K06-1616-R XXYY: Output Voltage, refer to Marking Information.
