MC79L15ACLP Application Field and Working Principle

MC79L15ACLP is a voltage regulator that belongs to the category of linear voltage regulators. It is a three-pin voltage regulator that operates within an input voltage range of 5 to 25 Volts and provides an output voltage that is adjustable between 1.2 and 15 Volts. The voltage regulating capability is obtained through an external resistor that is connected between the adjustment and output terminals. The range of output voltage can thus be adjusted to suit the particular application.

The three-pin regulator provides an input voltage that is within the given range and set to the output voltage. It provides a regulated output current of up to 100mA and a line and load regulation of 0.1%. Due to its small size, low drop out voltage and wide temperature operating range, this product is suitable for a range of different applications.

Application Field

The MC79L15ACLP is suitable for a variety of applications including but not limited to:

• Battery-powered digital electronics
• Regulated supply for LED lighting
• Voltage supply for door locks
• Portable electronics
• Power supply for industrial equipment
• Tracking systems
• Security systems

Working Principle

The MC79L15ACLP is a linear voltage regulator that utilizes the principles of negative feedback control. It consists of three pins, namely the input, adjustment, and output voltage pins. By connecting an external resistor between the adjustment and output pins, the range of output voltage can be adjusted. The device adjusts the output voltage to match the input voltage and provides a regulated output current of up to 100mA.

The device sees the input voltage and adjusts the output voltage accordingly. The output voltage is determined by the total resistance that is present in the circuit. The input voltage is then compared to the output voltage and an error voltage is generated. This error voltage is fed back to the device’s internal circuitry, where it initiates an adjustment in the output voltage.

The range of output voltage is adjustable over a range of 1.2 to 15 Volts. The device is capable of maintaining the output voltage with a line and load regulation of 0.1%. It has a low drop out voltage and a wide temperature operating range of -40°C to 85°C. This device is designed to be highly efficient, consuming very low quiescent current.

Conclusion

The MC79L15ACLP is a three-pin linear voltage regulator suitable for a range of applications. It is characterized by low drop out voltage and a wide temperature operating range of -40°C to 85°C. With an adjustable output voltage range of 1.2 to 15 Volts, it can provide a regulated output current of up to 100mA. Moreover, it features low quiescent current and a line and load regulation of 0.1%. This device is suitable for use in portable electronics, voice recognition systems, and many other applications.
