R1173x SERIES Super low on resistance/Low voltage LDO NO.EA-123-111027 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.

ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the life time and safety for both device and system using the device in the field. The functional operation at or over these absolute maximum ratings is not assured. RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 5 R1173x ELECTRICAL CHARACTERISTICS • R1173xxxxB/D (Fixed Output Voltage Type) Symbol Item VIN Input Voltage ISS Supply Current Istandby Standby Current VOUT ΔVOUT/ ΔIOUT Load regulation VDIF Dropout Voltage ΔVOUT/ ΔVIN Conditions Min.

For this purpose, use as much as a capacitor as C2. Recommendation value is as follows: Mounting on PCB Make VDD and GND lines sufficient. If their impedance is high, a current flows, the noise picked up or unstable operation may result. Further use a 4.7μF or more value capacitor between VDD pin and GND pin as close as possible. Set an Output capacitor between VOUT pin and GND pin for phase compensation as close as possible. Output Voltage C2 recommendation value VOUT
