R1172x SERIES SUPER LOW ON RESISTANCE / LOW VOLTAGE 1A LDO NO.EA-122-130924 OUTLINE The R1172x Series are CMOS-based positive voltage regulator ICs. The R1172x Series have features of super low dropout, 1A output current capability. Even the output voltage is set at 1.5V, on resistance of internal FET is typically 0.32. Therefore, applications that require a large current at small dropout are suitable for the R1172x 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 of R1172 is fixed in the IC. Since the packages for these ICs are SOT-23-5, SOT-89-5, HSON-6, and HSOP-6J with high power dissipation, 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. 4 R1172x ELECTRICAL CHARACTERISTICS * R1172xxx1A Symbol Topt=25C Item Conditions Min.

For this purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). The recommendation value is as follows. Output Voltage C2 recommendation value VOUT < 1.0V 1.0 < = VOUT < = 3.3V 3.3V < VOUT Components Recommendation Tantalum 4.7F or more Ceramic 4.7F or more Ceramic 4.7F or more Kyocera 4.7F (1608) Murata 4.7F (1608) Murata 10F (1608) Kyocera 4.7F (thin 2012) Murata 10F (2012) Part Number : CM105X5R475M06AB Part Number : GRM188R60J475KE19B Part Number : GRM188B30G106ME46B Part Number : CT21X5R475M06AB Part Number : GRM21BB30J106K If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable. Evaluate your circuit with considering frequency characteristics. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit with actual using capacitors. PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 with a capacitance value as much as 4.7F or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring as short as possible. 8 R1172x TYPICAL CHARACTERISTICS 1) Output Voltage vs. Output

VIN GND CIN Spectrum Analyzer ESR IOUT 0.8V to 3.3V Output type: COUT=4.7F (Kyocera CM105X5R475M06AB) 5.0V Output type : COUT=4.7F (Kyocera CT21X5R475K06AB) As an output capacitor for this IC, Ceramic capacitor is recommendable. However, other low ESR type capacitor can be used with this IC. For your reference, noise level is tested, and if the noise level is 40V or less than 40V, the ESR values are plotted as stable area. Upper limit is described in the next five graphs, or ESR vs. Output Current. (Hatched area is the stable area.)
