.. The combination of C 1 and R 5 implements a lowpass filter with a pole at approximately 10 Hz to remove power-supply noise. The following term describes the performance of IC 2 and its accompanying circuitry: V T = 75V S 3 V. ...
.. then pushed again. Thus, the promised push-ON/push-OFF functionality is delivered! The impedance of F1b’s pin 13 is supply-voltage dependent, ranging from 500 Ω at 5 V to 200 Ω at 15 V. If the current demand of the connected load is ...
.. protection is an obvious requirement for a power supply, especially when its load connects to a cable that's subject to damage. Many modern power-converter ICs ...
.. The transistors are preferably Darlington types and, like the diodes, should have adequate ratings to accommodate the power-supply voltage and the motor current. (Don't forget the high inductance of the motor.) The components in Figure ...
.. 2% precision of the LM317 internal voltage reference, making it securely independent of vagaries of both the 5-V logic supply rail and incoming raw DC supply. Figure 1 diagrams how it works. Figure 1. LM317 regulator melds with HC4053 ...
.. application for that device (see Figure 2 of its data sheet). The data-sheet circuit, however, is suitable only for supply voltages in the range +2.7 V to +5.5 V. You can extend that range to 28 V by adding a general-purpose NPN ...
.. flat, wideband response, and an output matching network including the transmission line to the output connector. The power supply block uses a charge pump and dual low-dropout (LDO) voltage regulator to supply positive and negative DC ...
.. around ~1% distortion (Figure 3). Figure 3. The scope image shows the oscillator output at circa 1 kHz. A variation in the supply voltage from 9 V to 12 V causes a frequency variation of only 2 Hz and a variation of output amplitude from ...
.. load resistors R A , R B , and R C yield four ranges of output-current capability. To set the range for a power-supply load, connect the positive lead of the supply to the + input of the load circuit and the negative load to one ...
