The MC78L12ACDR2 is a voltage regulator linear and belongs to the family of PMIC - Voltage Regulators - Linear. The MC78L12ACDR2 is a three-terminal fixed output negative voltage regulator and can deliver up to 100 mA of output current. It incorporates on-chip voltage reference and current limit circuit that can regulate and protect the output from excessive load currents. With its low output voltage of -12 V, the MC78L12ACDR2 is an excellent choice for applications specifically requiring a negative voltage, such as Motor-OLED driver and memory BIOS.

The MC78L12ACDR2’s application field includes digital devices, especially where low noise, low dropout voltage and low current drain are needed. Its on-chip voltage reference and current limit circuits eliminate external components and minimize design cost. It also has a typical temperature coefficient of ± 0.03%/℃ and an operating temperature range of 0° to 70°C.

Working Principle of MC78L12ACDR2: The MC78L12ACDR2 works on the basic principles of negative linear voltage regulation. It consists of an error amplifier and a series pass transistor, which creates an output voltage that is a fraction smaller than the reference voltage. It is designed to be a low-noise part, thus making it suitable for applications where noise-free operation is important.

When the output voltage is greater than its target voltage, the error amplifier drives the output current of the series pass transistor down and restricts the output voltage. On the other hand, when the output voltage is less than its target voltage, the error amplifier drives the output current of the series pass transistor up to increase the output voltage.

The MC78L12ACDR2 also offers additional features such as thermal protection, current limiting and thermal shutdown. These features can help protect the circuit from thermal damage caused by excessive current flow or excessive temperature rise.

Overall, the MC78L12ACDR2 is an ideal solution for applications requiring precise voltage regulation of -12 V. It offers excellent line regulation and minimized noise and ripple at the output, while being a cost-effective solution. Due to its low output voltage and small size, the MC78L12ACDR2 is an excellent choice for applications such as Motor-OLED driver, memory BIOS and handheld devices.
