Low Noise Power Supply LSI Series for Audio System
Ultra Low Noise Low Dropout Regulator for Audio System
BD37201NUX
General Description BD37201NUX is a low saturation series regulator of low noise (4.72µVrms) which is most suitable to high quality audio system. It operates at 2.7V to 5.5V and capable of supplying a maximum load of 500mA.
BD37201NUX has a high PSRR and good input transient fluctuation characteristic which makes it suitable for the stabilization of DC/DC converter output, and an ideal power supply to high precision analog circuits such as D/A converter (DAC) or Clock generator.
Furthermore, when BD37201NUX is placed in standby mode, the supply current can be as small as 0µA(Typ) which can greatly reduce power consumption.
