Under heavy overload conditions the output current limit folds back by 50% (typ) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Operating Voltage Range 2.4 5.5 V Output Voltage Accuracy VOUT ≥ 1.2V, TA = 25°C, IOUT = 10mA -1.5% VNOM 1.5% V Line Regulation VINL = Max (VOUT + 0.5V, 3.6V) to 5.5V, LOWIQ[ ] = [0] 0.5 mV/V Load Regulation IOUT = 1mA to IMAX2 0.08 V/A Power Supply Rejection Ratio f = 1kHz, IOUT = 20mA, VOUT =1.2V 80 dB f = 10kHz, IOUT = 20mA, VOUT =1.2V 70 Supply Current per Output Regulator Enabled 24 60 µA Regulator Disabled 0 Soft-Start Period VOUT = 3.0V 100 µs Power Good Threshold VOUT Rising 92 % Power Good Hysteresis VOUT Falling 4 % Output Noise IOUT = 20mA, f = 10Hz to 100kHz, VOUT = 1.2V 30 µVRMS Discharge Resistance LDO Disabled, DIS[ ] = 1 1.5 kΩ REG5 Dropout Voltage IOUT = 160mA, VOUT > 3.1V 130 200 mV Maximum Output Current 350 mA Current Limit VOUT = 95% of regulation voltage 385 550 mA Stable COUT5 Range 2.2 20 µF REG6 Dropout Voltage IOUT = 160mA, VOUT > 3.1V 130 200 mV Maximum Output Current 350 mA Current Limit VOUT = 95% of regulation voltage 385 550 mA Stable COUT6 Range 2.2 20 µF REG7 Dropout Voltage IOUT = 160mA, VOUT > 3.1V 160 300 mV Maximum Output Current 250 mA Current Limit VOUT = 95% of regulation voltage 275 400 mA Stable COUT7 Range 2.2 20 µF REG8 Dropout Voltage IOUT = 160mA, VOUT > 3.1V 160 300 mV Maximum Output Current 250 mA Current Limit VOUT = 95% of regulation voltage 275 400 mA Stable COUT8 Range 2.2 20 µF |
