The MAX8860EUA27+ is a linear voltage regulator from Maxim Integrated, specifically designed for power management applications in small, handheld and battery-powered devices. It has a large operating voltage range and high operating temperature, making it an ideal choice for a wide range of applications that require low power consumption. This article will discuss the application field and working principle of the MAX8860EUA27+.

Application Field

The MAX8860EUA27+ is a low-cost, high-efficiency linear voltage regulator designed to provide regulated output voltages from 3V to 24V in a tiny package. Its input voltage range can go up to 36V and its output is adjustable, allowing the device to be used in a variety of applications. It features integrated voltage sense and dual–output integration capabilities, enabling the use in low power, low voltage applications. The single output version of the MAX8860EUA27+ features a wide input voltage range, adjustable output voltage and current limit, making it suitable for battery-operated devices.

The device is also suitable for powering logic circuits and low-voltage logic circuits such as dynamic RAMs and microprocessors. It can be used in applications where the output voltage does not exceed 34V and can provide up to 24V at up to 200mA with a single output, making it suitable for a wide range of consumer electronics.

Other applications for the MAX8860EUA27+ include audio, video and automotive systems, powering preamps and actuators as well as test and measurement instruments. It is also well-suited for medical applications, as it can provide a clean, regulated output voltage of up to 24V while consuming very little power.

Working Principle

The MAX8860EUA27+ is a linear voltage regulator that uses an internal pass transistor to regulate the output voltage. The voltage regulator is designed to be a low dropout (LDO) type, which means it can regulate an output voltage that is very close to the input voltage. The device works by using the internal pass transistor to adjust the output voltage depending on the output current.

The output voltage is set by an external resistor divider connected to the ADJ pin on the device. The device will then compare this voltage to the input voltage on the VIN pin. If the output voltage is lower than the input voltage, the device will turn on the pass transistor, allowing more current to pass through the device, increasing the output voltage. If the output voltage is higher than the input voltage, the device will turn off the pass transistor, restricting the current passing through the device and decreasing the output voltage back to the desired level.

The MAX8860EUA27+ also features various protection features to ensure safe operation. It has over-current and over-voltage protections built-in, which protect the device and the load if the output voltage exceeds the specified limits. There is also thermal limiting, which will reduce the internal supply voltage if the temperature inside the device exceeds a certain level, protecting it from damage.

Conclusion

The MAX8860EUA27+ is a low-cost, high-efficiency linear voltage regulation device designed to provide regulated output voltages up to 24V and up to 200mA. The device is suitable for a wide range of applications, including consumer electronics, audio, video, automotive and medical applications. It features wide input voltage range, adjustable output voltage, current limit, various protection features and thermal limiting. The device is well-suited for small, handheld and battery-powered devices.
