15 volt stabilizer circuit

This document discusses a voltage stabilizer circuit utilizing the ICs 7815 and 7915, which requires an input voltage range of 17.5V to 50V. The output of this circuit consistently provides a regulated 15V output voltage. The stabilizer is further enhanced with the inclusion of transistors 2N3055 and MJ2955 for improved performance.

The voltage stabilizer circuit using IC 7815 and 7915 is designed to provide a stable output voltage of 15V, making it suitable for various applications requiring regulated power supply. The IC 7815 is a positive voltage regulator, while the IC 7915 serves as a negative voltage regulator. This configuration allows the circuit to handle both positive and negative voltage requirements, which is essential in many electronic systems.

The input voltage range of 17.5V to 50V is necessary to ensure that the regulators can operate effectively, as both ICs require a minimum input voltage that is higher than their output voltage to maintain regulation. The 7815 and 7915 regulators typically have dropout voltages around 2V, which means that for the output to remain stable at 15V, the input must be at least 17V.

The addition of power transistors 2N3055 and MJ2955 enhances the current handling capability of the circuit. These transistors are used in a complementary configuration to provide increased output current, allowing the circuit to supply higher loads without overheating or entering a state of thermal shutdown. The 2N3055 is a NPN transistor rated for 15A, while the MJ2955 is a PNP transistor with similar ratings, making them suitable for high-power applications.

The circuit typically includes bypass capacitors at the input and output of the voltage regulators to filter out noise and ensure stable operation. A heat sink is also recommended for the transistors to dissipate excess heat generated during operation, especially when delivering high currents. Proper thermal management is crucial to maintain the reliability and longevity of the circuit.

Overall, this voltage stabilizer circuit is an effective solution for applications requiring a reliable 15V output from a varying input voltage, supported by robust components to ensure durability and performance.In this time I will share about the circuit voltage stablizer or stabilization using IC 7815 and 7915, with a minimum of 17. 5V to 50V input.
