This Power Tip presents ... equivalent series resistance (ESR), and equivalent series inductance (ESL). The closed-loop output impedance is calculated by dividing the open-loop impedance by one plus ...

As [Electronoobs] points out, everything has resistance. So, how hard can it be to make a high-power resistor ... Maybe you need a dummy load, or you want to drain some batteries.

Conveniently, one quad op amp can be used with three power blocks. From here we can see that the effective load resistance R L is: By adjusting the divider ratio or substituting R 10 with a ...

These include the output-voltage temperature coefficient, initial accuracy, drift, noise, line and load regulation, package size and type, power consumption, stability with various capacitive ...

But to test a 300-A, 0.8-V power supply, at least four 63640-80-80 load modules must be combined in parallel—both to achieve an effective on-resistance below 2.7 mΩ and to handle the total current.
