The LDK130PU30R from STMicroelectronics is a 300mA low dropout linear regulator with a fixed 3.0V output. It features an exceptionally low 60 µA quiescent current, making it one of the most power-efficient options for battery-operated equipment. The 6-DFN package measures just 1.2x1.3mm, ideal for space-constrained designs. With 55dB PSRR from 120Hz to 10kHz, it delivers clean, stable power for audio, RF, and precision analog applications.
- Industry-Leading Low Power: 60 µA quiescent current dramatically extends battery life in always-on applications.
- Miniature Footprint: 1.2x1.3mm DFN package is ideal for wearables and medical implants.
- Broad Noise Rejection: 55dB PSRR across 120Hz-10kHz covers both mains hum and switching frequencies.
- Reliable Operation: 0.4V dropout at 300mA ensures stable output even with low input margins.
Ultra-Low-Power IoT Sensors
The 60 µA quiescent current is among the lowest in its class, making it perfect for always-on sensors, smart meters, and environmental monitors that run on coin cells.
Wearable Health Monitors
Compact 1.2x1.3mm DFN package and stable 3.0V output support continuous heart-rate, SpO2, and temperature monitoring in fitness bands and smartwatches.
Audio Processing Circuits
With 55dB PSRR across 120Hz-10kHz, it effectively isolates audio codecs and amplifiers from power supply hum and switching noise.
Energy Harvesting Systems
Low dropout of 0.4V allows operation from solar cells, thermoelectric generators, or piezoelectric harvesters with minimal voltage headroom.
Embedded MCU Boards
Provides a clean 3.0V rail for ARM Cortex-M and RISC-V microcontrollers in development boards and industrial control modules.
RF Transceiver Power
Stable output under dynamic load conditions ensures reliable operation of sub-1GHz and 2.4GHz wireless transceivers in smart home devices.
