5G14 3 ~ 6V adjustable power supply

As shown in the figures, this is a practical adjustable power supply. It utilizes an integrated voltage regulator (5G14) in conjunction with a 3DG12A transistor for current spreading, providing an output voltage range of 3 to 6V. The rated output current is 160mA, with a ripple factor of 1mV, making it suitable for powering radios and small recorders.

This adjustable power supply circuit is designed to deliver a stable output voltage between 3V and 6V, which is particularly useful for low-power applications such as portable radios and small audio recorders. The core of the design is the 5G14 voltage regulator, which is responsible for maintaining a consistent output voltage despite variations in input voltage or load conditions. The integration of the 3DG12A transistor enhances the current handling capability of the circuit, allowing it to provide a maximum output current of 160mA.

The ripple factor of 1mV indicates that the power supply produces minimal voltage fluctuations, ensuring clean and stable power delivery. This is crucial for sensitive electronic devices that may be adversely affected by power supply noise. The circuit can be adjusted to set the desired output voltage within the specified range, providing flexibility for various applications.

In terms of implementation, the circuit should include appropriate input and output capacitors to filter noise and stabilize the voltage levels. Additionally, heat dissipation considerations must be taken into account, particularly for the 3DG12A transistor, which may require a heatsink if the current load approaches its limits. Overall, this adjustable power supply circuit is an effective solution for powering low-voltage electronic devices with reliability and precision. As shown in FIG. 3 ~ 6V a practical adjustable power. The power supply to the integrated voltage regulator 5G14 core plus 3DG12A transistor current spreading, constitute an out put voltage of 3 ~ 6V, rated output current of 160mA tandem type power supply, the ripple factor 1mV, suitable for radio, small recorder power.
