Nisshinbo Micro Devices Inc. Voltage Regulators - Linear RP104K191D-TR

The RP104K191D-TR is a CMOS-based linear voltage regulator IC designed for applications requiring high output voltage accuracy and low supply current. It operates with a typical supply current of 1.0µA and a standby current of 0.1µA, making it suitable for battery-powered devices where prolonged battery life is essential. The device supports an input voltage range of 1.7V to 5.25V and provides an output voltage range from 1.2V to 3.3V in 0.1V increments. Key specifications include a dropout voltage of 0.24V at 150mA output current, a temperature-drift coefficient of output voltage at ±40ppm/°C, and line regulation of 0.02%/V. The RP104K191D-TR features built-in fold-back protection with a current limit of approximately 40mA during short mode. It is available in compact packages such as DFN(PLP)1010-4, SOT-23-5, and SC-82AB, facilitating high-density mounting on circuit boards. The use of ceramic capacitors of 0.1µF or more is recommended for optimal performance. This product is suitable for powering portable communication equipment, cameras, and other battery-operated devices.
