MAX5092AATE+T

Introduction

The MAX5092AATE+T is a triple output, very low dropout, low quiescent current linear regulator, designed in the CMOS process. It operates with an input voltage range of 5V to 20V and an output voltage of 2.5V, 3.3V and 5V in a space-saving TDFN-10 package. The low dropout voltage makes the device suitable for a wide range of applications, while its low quiescent current makes it suitable for battery-powered systems. This device is ideal for applications where battery life is critical.

Application Field

MAX5092AATE+T is suitable for many portable applications requiring output currents of up to 1.5A, such as digital camera, mobile phone and portable audio player. It also can be used in consumer electronics, such as DVD/CD player, game console and HDTV. MAX5092AATE+T can be used in industrial applications, such as industrial controls and electrical meters.

Working Principle

The MAX5092AATE+T works on the principle of linear voltage regulation. It is a three-terminal adjustable device, consisting of an input lead, an output lead and a ground lead. The device uses an internal series pass transistor to maintain the output voltage at a set level. A feedback mechanism is used to sense the output voltage and adjust the internal series pass transistor to maintain the output voltage at the set level. By adjusting the sense pin voltage, the output voltage can be precisely set.

In addition, the MAX5092AATE+T has an over-temperature protection (OTP) circuit to prevent the device from overheating. The OTP circuit shuts down the internal series pass transistor if the temperature rises above a safe level. The OTP circuit is activated by an external thermistor.

Conclusion

The MAX5092AATE+T is a triple output, very low dropout, low quiescent current linear regulator. It is suitable for many portable applications such as digital cameras, mobile phones and portable audio players. It also can be used in consumer electronics, industrial controls and electrical meters. The low dropout voltage and low quiescent current make it suitable for battery-powered systems.
