The RP114K181D-TR from Nisshinbo is a high-performance 300mA low dropout linear regulator delivering a fixed 1.8V output. Its ultra-compact DFN(PL)1010-4 package and 75 µA quiescent current make it an excellent choice for battery-powered and space-constrained applications. With 75dB PSRR at 1kHz and a low dropout voltage of 0.39V, it ensures clean, stable power for noise-sensitive circuits.
- Extended Battery Life: Ultra-low 75 µA quiescent current minimizes standby power consumption in portable devices.
- Clean Power Delivery: 75dB PSRR at 1kHz effectively filters supply noise for sensitive analog and RF circuits.
- Space-Saving Design: The 1.0mm x 1.0mm DFN package enables ultra-compact PCB layouts for wearables and IoT modules.
- High Efficiency at Load: Low 0.39V dropout at 300mA maintains regulation even with low input margins.
Portable Battery-Powered Devices
The low 75 µA quiescent current and 300mA output make it ideal for extending battery life in wearables, IoT sensors, and handheld instruments where every microamp matters.
Noise-Sensitive RF and Audio Circuits
With 75dB PSRR at 1kHz, this LDO effectively suppresses power supply ripple, ensuring clean power for RF transceivers, audio codecs, and precision analog front-ends.
Compact Space-Constrained Designs
The DFN(PL)1010-4 package (1.0mm x 1.0mm) is perfect for space-limited applications like earbuds, smart watches, and medical patches where board area is critical.
Microcontroller Power Supply
Provides stable 1.8V rail for low-power MCUs and digital logic, with fast transient response to handle dynamic load changes during processing tasks.
