Super low On resistance/ Low voltage LDO  
R1173x SERIES  
OUTLINE  
The R1173x Series are CMOS-based positive voltage regulator ICs. The R1173x Series have features of  
super low dropout, 1A output current capability, and -3mV typical load regulation at 1A. Even the output voltage  
is set at 1.5V, on resistance of internal FET is typically 0.32Ω. Therefore, applications that require a large current  
at small dropout are suitable for the R1173x series. Low input voltage is acceptable and low output voltage can  
be set. The minimum input voltage is 1.4V, and the lowest set output voltage is 0.8V. Each of these ICs consists  
of a voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit circuit at  
over-current, a chip enable circuit, a thermal-shutdown circuit, and so on. A stand-by mode with ultra low  
consumption current can be realized with the chip enable pin. The output voltage types of R1173 are fixed one in  
the IC and adjustable one (R1173x001x).  
Since the packages for these ICs are the SOT-89-5 package, HSON-6, or HSOP-6J, high density mounting of  
the ICs on boards is possible.

0.8V to 5.0V(Fixed output voltage type, except HSOP6J: only 0.8V to 3.5V type is available.) or  
adjustable. (R1173X001X)
