The basic principle of the three-terminal regulator adopts a series-type voltage regulator circuit. In the linear integrated voltage regulator, because the three-terminal voltage regulator has only three lead-out terminals, it has the advantages of fewer external components, convenient use, stable performance, and low price, so it is widely used. In the working process of the series-type regulated power supply circuit, the regulator tube is required to always be in an amplifying state. The current passing through the adjusting tube is equal to the load current, so an appropriate high-power tube must be selected as the adjusting tube, and a heat sink must be installed in accordance with the regulations. In order to prevent short circuit or long-term overload from burning the adjusting tube, the DC voltage stabilizer is generally equipped with short circuit protection and overload protection circuits. The purpose of the voltage regulator triode is to stabilize the voltage of the control board circuit. To prevent the circuit from being burnt due to excessive voltage.
When using, you must pay attention to the relationship between (VI) and (Vo). The fixed output voltage of the 78L05 series three-terminal regulator is 5V, and the input voltage is at least greater than 7V, so there is 2-3V between input and output. And above the pressure difference. Make sure that the adjustment tube works in the magnified area. However, when the pressure difference is large, the power consumption of the integrated block will be increased. Therefore, both should be taken into consideration, that is, it is ensured that the regulator tube does not enter saturation at the maximum load current, and the power consumption is not too large. In addition, a diode is generally connected to the input and output terminals of the three-terminal regulator to prevent the charge stored at the output terminal from passing through the regulator when the input terminal is short-circuited, and damaging the device.
