Extended output current application

Description: The 78 Series integrated voltage regulator has a rated output current of 1.5A. For applications requiring larger output currents, the output current can be increased using the square method. This method typically involves connecting multiple regulators of the same type in parallel, ensuring that each regulator shares the load evenly. Additionally, external power sources can be utilized alongside the regulator, as illustrated in Figure 7-200, which includes the connection to a diffuser tube with PNP polarity for power management. The integration of this configuration with an NPN regulator adjustment tube forms a composite circuit. The bias current for regulation is established through a bleeder resistor, which determines the minimum output current of the regulator.

The 78 Series integrated voltage regulator is designed to provide a stable output voltage with a maximum output current of 1.5A. It is commonly used in various electronic applications where a reliable power supply is essential. The square method for extending output current involves paralleling multiple regulators, which allows for increased current capacity without exceeding the individual regulator's limits. Each regulator in the parallel configuration must be matched to ensure uniform current distribution, preventing thermal overload and ensuring stability.

The external power source can be connected to the regulator's input, enabling the system to handle higher power demands. The PNP polarity configuration is crucial for the management of power in this setup, allowing for efficient control of the output voltage. The composite circuit formed by integrating the NPN regulator adjustment tube allows for fine-tuning of the output voltage, enhancing the overall performance of the power supply.

The bias current, supplied through the bleeder resistor, plays a critical role in maintaining the regulator's performance. This resistor helps to set the minimum output current, ensuring that the regulator operates within its specified parameters even under varying load conditions. Proper selection of the bleeder resistor value is essential for achieving the desired output characteristics and ensuring reliable operation of the entire circuit.

In summary, the 78 Series voltage regulator is a versatile component that can be adapted for higher output currents through parallel configurations and external power sources, making it suitable for a wide range of applications in electronic circuit design.78 Series integrated voltage regulator rated output current of 1.5A, For larger output current, the output current can be extended using the square method.
