R1190x Series
1A 16V Input VR
The R1190x Series are CMOS-based 16V input voltage regulators featuring 1A output. These are suitable for digital home appliances,
in which only bipolar types could previously operate. So R1190x contributes to save energy. R1190x has an inrush current limit
circuit that limits approximately 300mA when the voltage regulator turns on. It is also possible to set the inrush current limit time by
connecting a capacitor with DELAY pin. In addition to TO-252-5-P2 and HSOP-6J packages, a SOT-89-5 package with high-density
mounting is available.

R1190S/J Series are suitable for automotive applications too. Please refer to our "Car Electronics Products Catalog" or contact us.
