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.
The Ricoh R1190x Series are CMOS-based 16V input voltage regulators designed to provide 1A output current. These devices are suitable for digital home appliances and other applications where energy saving is a priority. The series features an inrush current limit circuit that restricts the initial surge to approximately 300mA, with the timing adjustable via an external capacitor on the DELAY pin.
