Supplier Device Package DFN(PL)1010-4B

The Nisshinbo RP114K151D-TRB is a high-performance 300mA low dropout linear regulator delivering a fixed 1.5V output. Its ultra-low 75 µA quiescent current and excellent 75dB PSRR at 1kHz make it ideal for battery-powered and noise-sensitive applications. Housed in a compact DFN(PL)1010-4B package, this LDO combines efficiency, stability, and minimal footprint for modern portable electronics.

  • Extended Battery Life: Ultra-low 75 µA quiescent current minimizes standby power draw, ideal for portable devices.
  • Clean Power Delivery: 75dB PSRR at 1kHz effectively suppresses input ripple, ensuring stable output for sensitive analog/RF circuits.
  • Compact Footprint: DFN(PL)1010-4B package (1.0mm x 1.0mm) saves critical board space in miniaturized designs.
  • Reliable 300mA Output: Sufficient current capability for MCUs, sensors, and low-power peripherals with stable regulation.

Portable Battery-Powered Devices

The low 75 µA quiescent current extends battery life in wearables, IoT sensors, and handheld instruments where standby power is critical.

RF and Analog Signal Chains

With 75dB PSRR at 1kHz, this LDO provides clean, stable power to sensitive analog-to-digital converters, op-amps, and RF transceivers, minimizing noise-induced errors.

Microcontroller Power Supply

Delivering a stable 1.5V rail at up to 300mA makes it ideal for powering low-voltage MCUs and digital logic in embedded systems.

Space-Constrained PCBs

The compact DFN(PL)1010-4B package (1.0mm x 1.0mm) suits dense designs like earbuds, smart cards, and medical patches where board area is at a premium.

Noise-Sensitive Audio Equipment

The high PSRR reduces power supply hum and ripple, ensuring clean audio performance in portable DACs and headphone amplifiers.

Always-On Power Domains

The ultra-low quiescent current supports always-on domains in smart home devices, preserving energy while maintaining system readiness.
