Introduction

The UA78M08CDCYR is a linear voltage regulator manufactured by ON Semiconductor. This device is designed to supply constant voltage over a wide range of input voltages and load conditions. It is ideal for applications requiring precise voltage regulation, high efficiency, and low power dissipation.

Application Field

The UA78M08CDCYR is a step-down voltage regulator for various power management applications. It can provide an output adjustable from 1V to 8V with a maximum current of 800mA. This makes it suitable for medium-power applications, such as those found in consumer electronics, automotive, and industrial applications.The UA78M08CDCYR is a cost-effective solution for applications requiring precise regulation of a low-power supply. It is well-suited for use in portable electronic devices such as cell phones, PDAs, and calculators. In addition, it can be used in automotive applications such as in power supplies and battery chargers.

Working Principle

The UA78M08CDCYR is a linear voltage regulator that operates on the concept of voltage regulation. It compares the output voltage with a reference voltage and adjusts the output accordingly. The reference voltage is derived from a precision reference source and sets the voltage output of the regulator.The UA78M08CDCYR uses a voltage divider network to compare the output voltage to the reference voltage. The output of the voltage divider is fed back to the regulator and compared to the reference voltage. If the output voltage is higher than the reference voltage, the output voltage is reduced accordingly. Conversely, if the output voltage is lower than the reference voltage, the output voltage is increased.The UA78M08CDCYR can also be used as a current limiter, preventing current overloads and protecting external components. The device is self-protected against short circuit, open circuit, and over temperature conditions.
