This LDO has ultra-high PSRR performance and extremely low output noise. It is designed for noise-sensitive applications (eg, PLL, VCO, mixer, low noise amplifier (LNA), power amplifier (PA), precision operational amplifier, ADC, DAC and other high-performance analog circuits).
Precautions for using the module(1) The module has no reverse connection and overvoltage protection, please buyers carefully check and compare the power supply and then power on, otherwise it will damage the module.(2) The heating of the linear power supply is mainly determined by the output voltage difference and the load current. Please choose and use the power supply module reasonably. Generally, you need to reserve 30% of the vacancy.(3) The module belongs to the step-down type module, the input voltage needs to be greater than the output 1V or more to stabilize the output.(4) The module generates heat during use, please purchasers to enhance heat dissipation according to the actual situation. When carrying a large load, the heat sink can be appropriately increased.(5) When using the module, it is recommended to add 100uF or larger electrolytic capacitors to the input and output terminals.(6) It is recommended to use our transformer and rectifier filter module, which can be used as a precision power supply.Frequently asked questionsQ: Can the module power the audio equipment?A: This power module is a high-quality power module, designed for powering RF equipment and high-end audio equipment.Q: Can the two outputs of the module be connected in parallel?A: When the two output voltages are the same, you can connect the two outputs in parallel. At this time, the maximum output current is 1000mA. It is not recommended to use the maximum current, and a certain margin is required.Q: Why can't I test the nominal ripple parameters? The measurement ripple is relatively large.A: First of all, you need to have the correct measurement method. You can search for the power supply ripple measurement method. There are many explanations. Secondly, the linear power supply can only suppress the ripple noise of the input signal, but it is not infinite. If you use a switching power supply input and the noise is large, the linear power supply will not play a big role, so the general linear power input is through the transformer Rectifying and filtering. This shop has a full set of transformer rectification and filtering linear power supply solutions and modules.About Prime Living
