RICOH R1190x Series 1A 16V Input VR Data Sheet User Guide

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 300m A 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.
