R1191x SERIES 300mA LDO REGULATOR with the Reverse Current Protection NO.EA-229-111026 OUTLINE R1191x Series are a low supply current voltage regulator with high output voltage accuracy. The maximum operating voltage is 16V. These ICs can switch to the fast mode and the low power mode by the low power / fast mode changer pin (ECO pin) without changing the output voltage value. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a short current limit circuit, a thermal shutdown circuit and a chip enable circuit. Moreover, the R1191x Series has the reverse current protection function, which protects the reverse current flow into VDD pin when the output pin voltage becomes higher than the VDD pin voltage. Thus it is suitable for the back-up circuit. Since the packages for these ICs are SOT-89-5, SOT-23-5 and DFN1616-6, therefore 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 R1191x ELECTRICAL CHARACTERISTICS VIN=VCE=Set VOUT+3.0V (Max.16V), CIN=2.2F, COUT=4.7F IOUT=1mA, unless otherwise noted.

C1: Ceramic Capacitor 2.2F Murata GRM32RB11E225KC01B C2: Ceramic Capacitor 4.7F Murata GCM31CR71E475KA40 6 R1191x TECHNICAL NOTES When using these ICs, consider the following points: * Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). (Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the PCB.) * 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 2.2F or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the capacitor C2, as close as possible to the ICs, and make wiring as short as possible. * Thermal Shutdown Function There is the built-in thermal-shutdown function in R1191x series. It discontinues operation of the IC when the junction temperature becomes over 150C (Typ.) and IC re-operates when the junction temperature under 130C (Typ.). If the temperature increasing keeps the IC repeats ON and OFF operating. The output becomes the pulse condition. * Chip Enable (CE) Circuit and High-speed/ Low Supply Current Switching (ECO) Circuit To maintain the stability of the output voltage, please do not use the intermediate electric potentials (the voltage values between VCEH and VCEL) for the CE pin and the ECO pin. The use of the intermediate electric potentials increases the supply current and causes the unstable output voltage. * Auto-discharge Function R1191xxxxD has adopted Auto-discharge function, which decreases the output voltage quickly to 0V by turning on the transistor between VOUT pin and GND pin when switching "Active" to "Standby" and releases the electrical charges accumulated in the external capacitor. 7 R1191x TEST CIRCUITS VDD C1 VOUT VOUT C2 V R1191x Series GND CE IOUT ECO C1=Ceramic 2.2F C2=Ceramic 4.7F Basic Test Circuit VDD ISS A C1 VOUT VOUT C2 R1191x Series GND CE ECO C1=Ceramic 2.2F C2=Ceramic 4.7F Test Circuit for Supply Current Pulse Generator P.G.
