.. is to say, just how “constant” is their output held against changes in applied voltage? Frequent and expert Design Idea (DI) commentator Ashutosh Sapre was kind enough to measure this parameter for a design of mine and share ...
.. is withdrawn first, and then the 5-V supply. Hence, one push button does both (sequential) ON and OFF functions. This Design Idea (DI) is intended for MCU-based projects. No additional components/circuitry are needed to implement this ...
.. circuit breaker, or you may damage the rectifier, filer chokes, or PCB (printed-circuit-board) traces. The circuit in this Design Idea inserts a current-limiting resistor in the capacitor’s charging path. It senses when the capacitor ...
.. minimize the effects of loading from making further contributions to instability. Nevertheless, the strong suit of this design is definitely its dynamic range. Precision? Not so much. Materials on the topic Datasheet Texas Instruments ...
.. I used the SamacSys component libraries (for IC1 and IC2) in this PCB project as usual. It saves a lot of time and prevents design mistakes which leads to a lower product cost. All SamacSys component libraries (Schematic symbols, PCB ...
.. designs for current mirror circuits have been an active topic recently here in Design Ideas (DIs). Usually, the mirror designer’s aim is to make the mirror’s input and output currents ...
.. Woodward’s “Ignoring the regulator’s reference” ( Ref. 1 ) Design Ideas (DI) (see Figure 1) is an excellent, working example of how to include a circuit in the feedback loop ...
.. being generated by Q4/C3/R13. (For more informative details of the circuit’s general operation, see the original Design Idea [ 1 ].) The ’scope traces in Figure 2 should clarify matters. Figure 2. Waveforms within the ...
