LDO regulator for audio

Nisshinbo Micro Devices has launched the MUSES100 series – low-noise, LDO voltage regulator targeted at home audio, professional audio, and portable audio equipment.

The MUSES100 series is a CMOS-based LDO regulator that operates with an input voltage range from2.5V to 5.5V, delivering an output voltage range from 1.2V to 5.0V and supporting an output currentof up to 600mA.

The series features a ripple rejection ratio of 90 dB at 1 kHz & 10 kHz and 80 dB at 100 kHz.

In addition, an ultra-low output noise voltage of just 3.0 μVrms, making it suitable for audio DACs and other audio equipment to ensure stable and noise-free audio output even under fluctuating power conditions.


The typical dropout voltage is 0.15V at 600mA, providing efficient voltage regulation with minimal power loss.

A thermal shutdown, under-voltage lockout (UVLO), and overcurrent protection mechanisms are included to ensure reliable operation.

Furthermore, it supports the use of film and aluminium electrolytic capacitors as these have better DC bias characteristics (less reduction in capacitance as the applied DC voltage increases).

The MUSES100 uses a DFN3030-8-QC package and is available  now.
