Nisshinbo Micro Devices Inc. Voltage Regulators - Linear RN5RF46AA-TR-FE

The RN5RF46AA-TR-FE is a CMOS-based linear voltage regulator IC designed for applications requiring high ripple rejection and low supply current. It operates with a typical supply current of 30OºA and a standby current of just 0.1OºA, making it suitable for battery-powered devices. The output voltage accuracy is ¬±2%, with a ripple rejection of approximately 60dB at 1kHz. This regulator supports an output voltage range from 1.2V to 6.0V in 0.1V increments and features a low dropout voltage of about 0.1V at 100mA output current, depending on the external transistor used. The device includes essential features such as a voltage reference unit, an error amplifier, and a chip enable function to conserve battery life during standby. It is packaged in a compact SOT-23-5 format, making it ideal for space-constrained applications. Typical applications include power sources for handheld communication devices, cameras, and various home appliances. The RN5RF46AA-TR-FE is designed to drive external transistors, with a current limit of 8mA for the external transistor drive pin.
