R1171S SERIES  
1.5A LDO REGULATOR FOR AUTOMOTIVE APPLICATIONS  
NO. EC-125-140213  
OUTLINE  
The R1171x Series are CMOS-based positive voltage regulator ICs. The R1171x Series have features of low  
dropout voltage, high output voltage accuracy, 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 shutdown circuit. The output voltage of R1171x 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.  
The R1171x Series are available in HSOP-6J package which supports high wattage.
