Power Supply IC for High Fidelity Audio

Negative Voltage Linear Regulator for

High Fidelity Audio

BD37215MUV

General Description

Key Specifications

BD37215MUV is a linear regulator of low noise

(5.1µVrms) which is most suitable to high quality audio

system. It operates at -16V to -3V and capable of

supplying a maximum load of 1000mA.

■

Input Voltage Range:

-16.0V to -3.0V

-15.0V to -1.0V

1.0A(Max)

Output Voltage Range:

Output Current:

Output Voltage Noise^{(Note 1)}

5.1µVrms(10Hz to 100kHz, Typ)

In addition to the low noise, BD37215MUV 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.

■

PSRR^{(Note 2)}: 90dB(1kHz, Typ), 55dB(1MHz, Typ)

Input Transient Response:

Standby Current:

3mV(1.0V/µs, Typ)

9.2µA(Typ)

Operating Temperature Range: -40°C to +85°C

(Note 1) C_BC=10µF, V_OUT= -1.0V, I_OUT=0.5A setting

(Note 2) C_OUT=47µF, V_OUT= -1.0V, I_OUT=0.5A setting

Package

VQFN020V4040

W(Typ) x D(Typ) x H(Max)

4.00mm x 4.00mm x 1.00mm

Furthermore, when BD37215MUV is placed in standby

mode, the supply current can be as small as

9.2µA(Typ) which can greatly reduce power consump-

tion.
