R1191H030B-T1-FE

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=2.2μF, COUT=4.7μF IOUT=1mA, unless otherwise noted. are applicable under the condition of −40°C ≤ Topt ≤ 85°C.
