R1180N231B-TR-YE

R1180x-Y Series 150 mA LDO Regulator for Industrial Applications NO.EA-340-210820 OUTLINE The R1180x is a CMOS-based voltage regulator IC with high output voltage accuracy, extremely low supply current, and low ON-resistance. This IC consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit which prevents the destruction by excess current, and so on. The output voltage is fixed with high accuracy. B version has a chip enable pin, therefore ultra-low consumption current standby mode can be realized with the pin. The R1180x is available in SOT-23-5 and SON1612-6 package which is possible to mount at high density. This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the screening at high temperature and the reliability test with extended hours. This line of products operate in a wide temperature range from low temperature to high temperature to support harsh environment applications.

ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause permanent damage 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 rating is not assured. RECOMMENDED OPERATING CONDITIONS Symbol Item Rating Unit VIN Input Voltage 1.7 to 6.0 V Ta Operating Temperature Range −50 to 105 °C RECOMMENDED OPERATING CONDITIONS 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 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 R1180x-Y NO.EA-340-210820 ELECTRICAL CHARACTERISTICS VIN=VSET+1.0V, CIN=1.0μF, COUT=0.1μF, unless otherwise noted.
