The MP2009EE-1.8-LF-P is a high-performance, fixed-output linear regulator from Monolithic Power Systems, delivering a precise 1.8V rail. Engineered for low-power and noise-sensitive applications, it supports up to 120mA of output current with a low typical dropout voltage of just 0.172V. Its ultra-low 90 μA quiescent current significantly extends battery life in portable devices. The regulator offers excellent power supply rejection (78dB at 1kHz), ensuring clean and stable power for sensitive analog and RF circuits. Housed in a compact SC-70-5 package, it is an ideal solution for space-constrained designs requiring reliable and efficient voltage regulation.
- Extended Battery Life: Ultra-low 90 μA quiescent current minimizes power draw in standby and light-load conditions, ideal for battery-powered devices.
- Clean Power Delivery: High PSRR (78dB at 1kHz) effectively suppresses input noise, ensuring stable operation for sensitive analog and RF components.
- High Efficiency at Low Dropout: A typical dropout voltage of only 0.172V at 120mA allows operation closer to the output voltage, reducing power dissipation and improving efficiency.
- Compact Form Factor: The small SC-70-5 package saves critical board space, enabling miniaturized product designs without compromising performance.
Portable and Battery-Powered Devices
The low 90 μA quiescent current and 120mA output capability make it ideal for extending battery life in wearables, IoT sensors, and portable medical devices where power efficiency is critical.
Noise-Sensitive Analog Circuits
With a high PSRR of 78dB at 1kHz, this LDO effectively filters power supply noise, ensuring clean, stable voltage for precision analog-to-digital converters (ADCs), operational amplifiers, and sensor signal conditioning circuits.
Low-Power Microcontrollers (MCUs)
Provide a stable 1.8V rail for low-voltage MCUs and digital logic. The low dropout voltage of 0.172V maximizes efficiency when operating from a 2.5V or 3.3V battery source.
Wireless Communication Modules
Maintain a clean power supply for RF transceivers and Bluetooth/Wi-Fi modules. The excellent PSRR across 1kHz to 100kHz helps prevent interference and maintains signal integrity.
Space-Constrained Designs
The ultra-compact SC-70-5 package (2mm x 2.1mm) is perfect for space-limited PCBs in earbuds, smart cards, and compact handheld instruments, requiring minimal external components.
Industrial Sensor Interfaces
Regulate power for industrial sensors and transmitters where a stable, noise-free 1.8V reference is required for accurate measurement and reliable operation in electrically noisy environments.
