Frequently Asked Questions
What is the minimum input voltage required to operate the LD56100DPU15R at full 1 A load?
The LD56100DPU15R requires a minimum input voltage of 2 V and has a typical dropout voltage of 0.5 V, so the output voltage plus 0.5 V determines the minimum input needed at 1 A load. The absolute maximum input is 7 V, and the recommended operating range is 2 V to 5.5 V.
Which noise-sensitive applications benefit most from the LD56100DPU15R's ultra-low noise output?
Precision analog front ends, RF transceivers, and high-resolution ADCs operating at 16-bit or higher benefit greatly from the LD56100DPU15R's ultra-low noise LDO. The regulator's low output noise minimizes interference on sensitive supply rails, making it suitable for audio processing and medical sensor circuits requiring sub-millivolt ripple.
How does the LD56100DPU15R's 0.5 V dropout compare to standard LDO regulators in battery-powered designs?
Standard LDO regulators typically have dropout voltages of 1 V to 1.5 V, while the LD56100DPU15R achieves only 0.5 V typical dropout at 1 A output. This 50% or greater reduction in dropout enables longer battery runtime in single-cell Li-ion designs operating between 3 V and 4.2 V input, extending usable discharge cycles by hundreds of millivolts compared to conventional LDOs.
