TPS7A4701/TPS7A3301 Ultra-low ripple positive negative adjustable power supply module LDO voltage regulator module Circuit power
Application range:
1MHz-400MHz DDS signal generator, 1Hz-10GHz detector, DC-6GHz RF signal amplifier, used for operational amplifier (OP Amp), high-precision digital-to-analog converter (DAC), analog-to-digital converter (ADC), and others Power rails for high-precision analog circuits, audio signal amplifiers, post-DC/DC converter adjustment and ripple filtering, test and measurement, medical, industrial instrumentation, base stations and telecommunications infrastructure, 12V and 24V industrial bus , Sensor modules, wireless transparent transmission modules, filters, operational amplifiers (addition, subtraction, multiplication, and integration), relay modules, power modules, digital attenuators, frequency source phase-locked loops.
Precautions for module use:
1. The module has no reverse connection and overvoltage protection, please check carefully and compare the power supply before powering on, otherwise the module will be damaged.
2. The heating of the linear power supply is mainly determined by the input and output voltage difference and the load current. Please select and use the power module reasonably. Generally, a margin of 30% is required.
3. The module is a step-down module, and the input voltage needs to be greater than the output 0.5V for stable output.
4. When the load is large or the pressure difference is large, heat dissipation measures can be appropriately increased, otherwise the chip will be overheated or damaged.
Frequently Asked Questions:
1. Can the module be powered by audio equipment?
This power supply module is a high-quality power supply module designed to power radio frequency equipment and high-end audio equipment.
2. Why can't the output voltage of the module be greater than the input voltage?
The module is a step-down module and cannot be boosted; the maximum output voltage will be less than the input voltage about 0.5V.
3. Why can't I test the nominal ripple parameters? There is a gap in the measured ripple.
First, you need to have a correct measurement method, you can Google the power ripple measurement method by yourself. Secondly, the linear power supply can only suppress the input signal ripple and noise, but it is not infinite. It is recommended to use a general low-frequency (power frequency) transformer rectifier filter as the input. Of course, a switching power supply can also be used as a power supply.
