The RP114K181D5-TR is a low dropout linear regulator from Nisshinbo, delivering a fixed 1.85V output with up to 300mA of current. Its ultra-compact DFN(PL)1010-4 package and low 75 μA quiescent current make it ideal for battery-powered and space-constrained designs. With 75dB PSRR at 1kHz, it ensures clean 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 input noise, ensuring stable operation for analog and RF circuits.
- Space-Saving Footprint: The 1.0mm x 1.0mm DFN(PL)1010-4 package is ideal for miniaturized PCB designs.
- High Efficiency at Low Dropout: 0.39V dropout at 300mA allows operation from lower input rails, reducing power dissipation.
Portable Battery-Powered Devices
The low quiescent current of 75 μA extends battery life in wearables, IoT sensors, and handheld instruments where standby power is critical.
Noise-Sensitive Analog Circuits
With 75dB PSRR at 1kHz, this LDO provides clean, stable power for precision analog-to-digital converters, op-amps, and sensor signal conditioning.
Compact PCB Designs
The ultra-small DFN(PL)1010-4 package (1.0mm x 1.0mm) enables dense board layouts in space-constrained applications like earbuds, smart watches, and medical patches.
Microcontroller Power Supply
Delivering a stable 1.85V rail at up to 300mA, it is ideal for low-voltage MCUs and digital logic requiring tight voltage regulation.
