Power Supply IC for High Fidelity Audio

Linear Regulator for High Fidelity Audio

BD37201NUX

General Description

Key Specifications

BD37201NUX is a linear regulator of low noise (3.3

µVrms) which is most suitable to high quality audio

system. It operates at 2.7 V to 5.5 V and capable of

supplying a maximum load of 500 mA.

■

Input Voltage Range:

2.7 V to 5.5 V

1.0 V to 4.5 V

500 mA(Max)

Output Voltage Range:

Output Current:

Output Voltage Noise^{(Note 1)}

3.3 µVrms(10 Hz to 100 kHz, Typ)

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

Input Transient Response: 3 mV(1.0 V/µs, Typ)

In addition to the low noise, 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) and Clock generator.

■

Standby Current:

0.02 µA(Typ)

Operating Temperature Range: -10 °C to +85 °C

(Note 1) C_BC=10 µF, V_OUT=1 V, I_OUT=500 mA setting

(Note 2) C_OUT1=47 µF, C_OUT2=100 µF, V_OUT=1 V, I_OUT=500 mA setting

Furthermore, when BD37201NUX is placed in standby

mode, the supply current can be as small as 0.02 µA

(Typ) which can greatly reduce power consumption.
