TPS7A4701 DC-DC Low Noise Linear Step-down Buck Power Module Dual 5V 9V 12V 15V

TPS7A4701 DC-DC Low Noise Linear Step-down Buck Power Supply Module

Dual 5V 9V 12V 15V Output For Audio Amplifier DAC ADC RF OPamp

 



Description:

 

TPS7A4701 is a positive voltage (35V), ultra-low noise (4 μVRMS) low voltage drop linear voltage regulator (LDO), with 1A load current filling capacity. This linear power module developed by our shop based on this chip is equipped with two TPS7A4701 chips, and the dual outputs (with the same voltage) can be connected in parallel to improve the output capacity (2A); Compact and convenient, simple wiring, it is very suitable for power supply of operational amplifier, digital to analog converter (DAC), analog to digital converter (ADC), audio frequency, radio frequency and other high-precision analog circuits.

Application: Operational amplifier, digital to analog converter (DAC), analog to digital converter (ADC), audio, RF and other high precision analog circuit power supply.



Notice:

 

1> The module has no reverse connection protection and overvoltage protection. Please carefully check the input power parameters before use to avoid damage to the module.

 

2> The heating of linear power supply is mainly determined by the difference of input and output voltage and load current, so please select and use this power module reasonably, and generally reserve 30% margin.

 

3> This is a step-down power module, and the input voltage must be more than 1V higher than the output voltage to ensure stable output.

 

4> When the load or voltage difference is large, the heat dissipation must be strengthened, otherwise the chip will be overheated protection or damaged.

 

5> When the input power supply is greater than 16V, it is recommended to install a filter capacitor in front of the input terminal, recommend 50V 220UF.
