The circuits. To produce any output voltage, an external feedback resistors can be added. The sLM2576 is a Switching Regulator that can produce 15, 12, 5, 0r 3.3V output voltage from maximum supply voltage of 60V or 40V. This LM2476 featured with voltage reference, switch and feedback path for use in either the negative boost or the buck saturation voltage […]

The LM9070 is a 5V, 3% accurate voltage regulator which have 250mA low-dropout. The regulator has an active low delayed reset output flag feature. This feature can be used to reset microprocessor system on turn-ON and in the event that the regulator output falls out of regulation for any season. Before the reset output can return high, an external capacitor […]

The schematic diagram below show us a circuit of a battery-powered voltage reference that draws only 17uA of supply current. Two AA cells can power this reference over 18 months at this level. Drift of the reference is only at 5.5 uV/°C over the industrial temperature range at an output voltage of 1.23 V @25°C. The load regulation is 85 […]

The benefit of stepping down the voltage of the battery is that we can give a constant/stable performance for our devices until the battery runs out the power. That’s only one example of voltage regulation, actually there can be more advantage depends on your need. Here is one example of voltage regulator circuit constructed from discrete components: This is a […]
