R1171x SERIES  
2.0A/1.5A LDO REGULATOR  
OUTLINE  
NO. EA-125-061222  
The R1171x Series are CMOS-based positive voltage regulator ICs. The R1171x Series have features of low  
dropout voltage, high output voltage accuracy, and low consumption current. Each of these ICs consists of a  
voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit circuit at short  
mode, a chip enable circuit, and thermal-shunt circuit. The output voltage of R1171 is fixed in the IC.  
Low consumption current by the merit of CMOS process and built-in transistors with low ON-resistance make  
low dropout voltage and chip enable function prolongs the battery life. These regulators are remarkable  
improvement on the current regulators in terms of input transient response, and load transient response.  
Thus, the R1171x Series are suitable for various power sources.  
Since the packages for these ICs are high wattage HSOP-6J package, TO-252-5, high density mounting of the  
ICs on boards is possible.  
FEATURES  
• Low Supply Current......................................................Typ. 130µA  
• Low Standby Current....................................................Typ. 0.1µA  
• Output Current..............................................................Min. 1.5A (VIN=VOUT+1.0V, R1171SxxxA/B)  
Min. 2.0A (VIN=VOUT+1.0V, R1171JxxxC/D)  
• Input Voltage.................................................................2.1V to 6.0V  
• Output Voltage..............................................................1.5V to 5.0V (R1171SxxxA/B)  
1.8V to 5.0V (R1171JxxxC/D)  
• Output Voltage Accuracy.............................................. 2.0%  
• Low Dropout Voltage....................................................Typ. 0.09V (VOUT=3.0V, IOUT=300mA)  
• Low Temperature-drift Coefficient of Output Voltage ...Typ. 100ppm/°C  
• Line Regulation ............................................................Typ. 0.05%/V  
• Packages......................................................................HSOP-6J, TO-252-5  
• Built-in Current Limit Circuit  
• Built-in Thermal Shunt Circuit  
• Ceramic capacitor for phase compensation.................CIN=COUT=Ceramic 10.0µF (VOUT<1.8V)  
>
CIN=COUT=Ceramic 4.7µF (VOUT 1.8V)
