Linear Regulator for High Fidelity Audio - BD37210MUV (New)

BD37210MUV is a linear regulator of low noise (4.6μVrms) which is most suitable to high quality audio system. It operates at 3V to 16V and capable of supplying a maximum load of 1000mA. In addition to the low noise, BD37210MUV 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 operational amplifier and headphone amplifier for audio. Furthermore, when BD37210MUV is placed in standby mode, the supply current can be as small as 5.8μA(Typ) which can greatly reduce power consumption.
