The MP6402DN-EF-LF from Monolithic Power Systems is a dual 500mA adjustable LDO regulator. It operates from an input voltage as low as 0.9V, making it ideal for battery-powered applications. With a typical dropout of only 0.26V at full load and a quiescent current of 580 µA, it balances efficiency with clean output. The 8-SOICE package supports compact PCB layouts.
- Extended Battery Life: 580 µA quiescent current minimizes idle drain, ideal for always-on devices.
- Low Dropout: 0.26V typical at 500mA ensures regulation even when input voltage is close to output.
- Dual Output: Two 500mA channels reduce component count in multi-rail designs.
- High PSRR: 60dB at 100Hz filters mains hum for clean analog supplies.
Battery-Powered IoT Devices
The low 0.9V minimum input voltage allows operation from a single-cell alkaline battery down to near end-of-life, while the 580 µA quiescent current extends standby time.
Dual-Rail Microcontroller Systems
With two 500mA outputs, this LDO can power separate analog and digital supply rails for MCUs, reducing noise coupling between domains.
Portable Medical Monitors
The 60dB PSRR at 100Hz effectively rejects mains-frequency ripple, ensuring stable voltage for sensitive biosignal amplifiers.
Automotive Infotainment Backup
Its wide input tolerance (down to 0.9V) supports cranking conditions where battery voltage dips, maintaining a clean 3.3V rail for head units.
Industrial Sensor Nodes
The 8-SOICE package with exposed pad aids thermal dissipation, allowing continuous 500mA operation in enclosed enclosures up to 85°C.
FPGA Core Supplies
Dual 500mA outputs can power both VCCINT and VCCAUX rails of small FPGAs, simplifying power sequencing with independent enable pins.
