• UA78M12CKTPR Application Field and Working Principle:

The linear UA78M12CKTPR application field is designed to provide regulated power supply in various power applications. The understanding of its working principle can help in making the most of the device while powering up various circuits. There are numerous applications that make use of the UA78M12CKTPR integrated circuit, including data acquisition systems, computer peripherals, and automotive systems. The linear UA78M12CKTPR voltage regulator is built with a quiescent current architecture that operates effectively at wide ranges of supply voltages. This ensures best power regulation, even with a high output load. The modern low dropout linear regulator uses a series PNP pass device with a complementary NPN transistor, which allows for low power operation with good power rating. The quiescent current through the pass device is typically less than 500μA, whereas the voltage drop from its regulated output is typically less than 0.2V. The output voltage of the UA78M12CKTPR is set by a combination of the adjustable feedback resistor and its internal reference voltage, which is typically 1.2V. As the feedback resistance increases, the output voltage increases, and when the feedback resistance decreases, the output voltage of the device decreases as well. If the feedback resistance is not connected properly, the output voltage can be very low. The output voltage range of the device is typically 2.5V to 16V, depending on the manufacturer.The UA78M12CKTPR also has a built-in thermal shut down feature. This keeps the device from getting too hot while regulating the power. When the temperature threshold is reached, the device shuts down and re-starts when it is safe to do so. The deep sleep mode of the device helps to reduce the total power usage. When the input voltage drops below a preset threshold, the device automatically enters into the deep sleep mode, which reduces the quiescent current. The interconnections of the device are also quite easy. It requires two external resistors to set the feedback voltage and one external capacitor to decouple the device from any voltage spikes. The capacitance of this capacitor should be chosen according to the maximum output current. The common-mode rejection of this device is also quite high, typically greater than 90 dB. The quiescent current of the device is also lower than most of the others available in the market. In conclusion, the UA78M12CKTPR linear voltage regulator is a cost-effective solution for providing regulated power supply to many different applications. Its capability of operating at wide supply voltage ranges and its low dropout LDO architecture makes it suitable for powering many different circuits. The thermal shutdown feature and deep sleep mode of the device makes it an ideal choice for applications wherein power savings is an important criteria.
