MC79L12ABPRA application field and working principle

The MC79L12ABPRA is a fixed output, positive voltage regulator of the Low Dropout type. It is developed by Motorola Corporation and is intended for general purpose use. It is available as a 3-pin surface mount package. It is a surface-mount voltage regulator with an adjustable regulated output voltage range of 1.20V to 37V. It features logic control over the output voltage and thermal protection, making it ideal for portable applications that must withstand mobile conditions. This regulator operates over a wide input voltage range of up to 40V and delivers up to 800mA of output current. It is primarly intended for applications such as cellular phones, digital cameras, battery-powered and handheld electronic devices.

The working principle of the MC79L12ABPRA is based on the voltage regulator concept. When the output voltage of the regulator is lower than the input voltage, the back-biased diode is forward biased and acts as an output switch. This switch transfers power from the input to the output and regulates the output voltage. The voltage regulator also employs a series of feedback circuits and transistors to provide output voltage stability.

The input voltage is usually in excess of the required output voltage, so for the efficiency and stability of the circuit, the voltage regulator chip acts as a current limiter by blocking any current from the input to the output. In addition, the MC79L12ABPRA voltage regulator chip also features thermal protection to prevent damage to the device due to high-temperature operating conditions. It includes a temperature-sensing element and an over-current protection circuit.

The MC79L12ABPRA voltage regulator can be used in various applications including battery-powered applications, automotive applications, industrial motor control systems, power conversion systems, power supplies and medical equipment. Its adjustable output voltage range of 1.20 V to 37 V makes it suitable for a wide range of applications. It is a reliable, low-power device suitable for low-noise and low-ripple applications.

In summary, the MC79L12ABPRA is a fixed output, positive voltage regulator of the Low Dropout type. It has a wide input voltage range of up to 40V and delivers up to 800mA of output current. It features logic control over the output voltage and thermal protection, making it ideal for portable applications that must withstand mobile conditions. Its adjustable output voltage range of 1.20 V to 37 V makes it suitable for a wide range of applications.
