The RP114K301D-TRB from Nisshinbo is a 300mA low dropout linear regulator delivering a fixed 3.0V output. Its ultra-compact DFN(PL)1010-4B package and 75 µA quiescent current make it an excellent choice for battery-powered and space-limited designs. With a dropout voltage of just 0.22V at full load, it maintains regulation even with low input margins, ensuring reliable performance across portable electronics, IoT devices, and wearable technology.
- Extended Battery Life: 75 µA quiescent current minimizes standby drain, ideal for always-on applications.
- Space-Saving Footprint: 1.0mm x 1.0mm DFN package fits into the tightest PCB layouts.
- Low Dropout Operation: 0.22V dropout at 300mA allows operation close to the output voltage, improving efficiency.
- Stable 3.0V Rail: Fixed output ensures consistent performance without external resistor dividers.
Portable Battery-Powered Devices
The 3.0V fixed output and 75 µA quiescent current make it ideal for extending battery life in wearables, remote controls, and IoT sensors where standby power is critical.
Noise-Sensitive Analog Circuits
With a low dropout of 0.22V at 300mA, this LDO maintains a stable 3.0V rail even as the battery discharges, ensuring consistent performance for op-amps and ADCs.
Compact PCB Designs
The DFN(PL)1010-4B package (1.0mm x 1.0mm) is perfect for space-constrained applications like hearing aids, smart earbuds, and medical patches.
Microcontroller Power Supply
Provides a clean 3.0V supply for MCUs and digital logic, with 300mA capacity sufficient for most low-power microcontrollers and peripheral loads.
Wireless Communication Modules
Stable output under transient loads supports BLE, Zigbee, and sub-GHz transceivers, preventing brownouts during RF bursts.
Automotive Interior Electronics
While not AEC-Q100 qualified, the low quiescent current suits always-on modules like tire pressure sensors and key fobs in vehicle environments.
