Abstract
The utility model discloses a button type voltage regulator for outputting a step voltage. The button type voltage regulator comprises a voltage regulating circuit with a voltage regulating integrated circuit 317 as a core, an output terminal of the voltage regulating integrated circuit 317 is connected with a voltage regulating pin of the voltage regulating integrated circuit 317 via a first voltage regulating resistance, a second voltage regulating resistance is connected between the voltage regulating pin of the voltage regulating integrated circuit 317 and the ground, the button type voltage regulator also comprises: several potentiometers and switches with the same number as that of the potentiometers, each potentiometer and each switch are in series and then are in a parallel connection with the first voltage regulating resistance. The switches are normally-open reset switches. The button type voltage regulator is provided with beneficial effects of high precision of voltage output, high regulating speed, and long service lifetime.
Description
Technical field
The utility model relates to a kind of voltage regulator.
Background technology
Existing voltage regulator is normally regulated by potentiometer and is obtained different voltages, and useful life is short, if during for a plurality of different voltage of needs continuous wave output, goes back the special charges time, inefficiency.
The utility model content
The utility model provides a kind of button voltage regulator of exporting stepped-up voltage in order to overcome above deficiency, exports different voltage by button.
The technical solution of the utility model is:
A kind of button voltage regulator of exporting stepped-up voltage, comprise the regulating circuit take pressure regulation integrated circuit 31 7 as core, the output of pressure regulation integrated circuit 317 is connected with the pressure regulation pin of pressure regulation integrated circuit 317 through the first regulating resistor, the second regulating resistor is connected between the pressure regulation pin and ground of pressure regulation integrated circuit 317, also comprise: in parallel with the first regulating resistor after several potentiometers and the switch identical with potentiometer quantity, each potentiometer are connected with each switch.
Described switch is for often driving reset switch.
The utlity model has that the Voltage-output precision is high, governing speed is fast, the beneficial effect of long service life.
Description of drawings
Fig. 1 is the electrical schematic diagram of the button voltage regulator of the utility model output stepped-up voltage.
Embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figure 1, a kind of button voltage regulator of exporting stepped-up voltage, comprise the regulating circuit take pressure regulation integrated circuit 317 as core, input is the direct voltage UI after voltage stabilizing, the output UO of pressure regulation integrated circuit 317 is connected with the pressure regulation pin of pressure regulation integrated circuit 317 through the first regulating resistor R1, the second regulating resistor R2 is connected between the pressure regulation pin and ground of pressure regulation integrated circuit 317, also comprise: in parallel with the first regulating resistor R1 after several potentiometers W and the K switch identical with potentiometer quantity, each potentiometer W connect with each K switch.
Reset switch is often driven in the K switch choosing, and optional touching often driven reset switch.
Select the first regulating resistor R1, the second rational resistance of regulating resistor R2, can export initial fundamental voltage, an exportable different voltage again after potentiometer W and K switch parallel connection, after several potentiometers W and K switch parallel connection, each potentiometer W regulates reasonably value, exportable several different stepped-up voltages.
During use, several reset switch word orders, the button just as playing the piano, exportable a plurality of different voltages that regulate in advance, it is quite convenient to use.
