R1170x SERIES 800mA LDO REGULATOR NO.EA-084-111027 OUTLINE The R1170x Series are positive voltage regulator ICs by CMOS process. The R1170x 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 R1170x Series are suitable for various power sources for portable appliances. 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. 4 R1170x ELECTRICAL CHARACTERISTICS * R1170xxxxA Symbol Topt=25C Item Conditions Min.

For this purpose, use as much as 10F Capacitor as CL. 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. Further, refer to the Typical Characteristics No. 12. 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 as much as 10F 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.

For your reference, noise level is tested with the circuit as shown above, 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 four graphs, or ESR vs. Output Current. (Hatched area is the stable area.)
