Introduction

The L78M10CV is a three-terminal linear voltage regulator providing over-voltage, over-current and over-temperature protection. It is an integrated circuit made by STMicroelectronics, in the family of Power Management Integrated Circuit (PMIC) line. It belongs to the Voltage Regulators - Linear subfamily and is an ideal choice for various applications. This article will discuss the application field and working principle of L78M10CV.

Application Field

The L78M10CV is a voltage regulator that is used in many applications requiring a constant output voltage. Its main application fields include industrial control, point-of-load (POL) regulation and power supplies. In industrial control, it is used in AC-DC converter circuits, voltage references and current sources. In POL regulation, it is used as a voltage regulator in a power system rear-end equipment, such as servers, laptops, and board computers. Finally, in power supplies, its main application is to provide an adjustable and stable output voltage with low ripple and wide range selection options.

Working Principle

The operation of the L78M10CV is based on the three-terminal voltage regulator principle. This regulator consists of an amplifier that has a stability feedback loop created with resistors. The input voltage is applied to the input pin and the output voltage is developed across the output pin. The control pin is connected to a reference voltage and its output is compared to the input voltage to maintain a stable output voltage. This reference voltage is provided by a Zener diode connected between the output of the amplifier and the control pin.The amplifier has a long time-constant to minimize the noise and transient ripple on the output voltage. In addition, a frequency compensation zener diode is connected from the output of the amplifier to the control pin, resulting in a much better dynamic response.The amplifier also includes an over-current protection circuit that shuts down the regulator when the output current exceeds a certain threshold. This is necessary to prevent damage to the circuit due to excessive current.

Conclusion

The L78M10CV is a three-terminal linear voltage regulator used in various applications. Its main application fields are in industrial control, point-of-load regulation, and power supplies. The operation of the L78M10CV is based on the three-terminal voltage regulator principle, which consists of an amplifier with a stability feedback and a Zener diode connected between the output of the amplifier and control pin to provide the regulator\'s reference voltage. The amplifier also includes an over-current protection circuit to prevent damage to the circuit due to excessive current.
