800mA LDO REGULATOR  
R1170X series  
OUTLINE  
The R1170 Series are positive voltage regulator ICs by CMOS process. The R1170 Series have features of  
high ripple rejection, 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-shunt circuit. Output Voltage of R1170 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 prolong the battery life. These regulators are remarkable improvement  
on the current regulators in terms of ripple rejection, input transient response, and load transient response.  
Maximum Output Current is large for its compact size.  
Thus, the R1170 Series are suitable for various power sources for portable appliances.  
Since the packages for these ICs are the SOT-89-5 package or HSON6, high density mounting of the ICs on  
boards is possible.
