R1190x SERIES
1A
REGULATOR
(Operating Voltage up to 16V)
No.EA-183-090206
OUTLINE
The R1190x series are a low supply current voltage regulator with high output voltage accuracy. The maximum
operating voltage is 16V. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net
for voltage setting, as a short current protection, a peak current protection, a thermal shutdown, an inrush current
limit and a chip enable circuit. The wide input voltage range (Max. 16V). Additionally, the output voltage is fixed
internally, in the range from 2.0V to 12.0V by the 0.1V steps. The supply current of R1190x series is excellent
(Typ.150μA) moreover R1190x series has the standby mode (Typ.0.1μA) by the chip enable function.
Since the package for these ICs are TO-252-5-P2, SOT-89-5 and HSOP-6J with high power dissipation, high
density mounting of the ICs on boards is possible.

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.
