Introduction

The MAX1589ETT250+T device is a linear voltage regulator from Texas Instruments, designed to provide up to 250mA of output current in a low-cost and thermally efficient thermally enhanced ThinSOT™ package. The device operates from a nominal input of 3.0V to 18V, capable of providing output voltages of 1.8V to 5V with a ±1.5% accuracy. PWM noise reduction and loop stability are achieved through the use of an internal analog compensation circuit. The low quiescent current of 95uA, low temperature coefficient of 0.03%, and an internal current limit of 1A ensure high reliability and safety when operating in harsh environments.

Application Field

The MAX1589ETT250+T is an ideal solution for a variety of low power applications. It can be used to regulate line ups in consumer devices such as digital cameras, MP3 players, and mobile phones. It is also suited for 5V regulated supplies in automotive, industrial and other general-purpose applications. Additional features such as low dropout voltage, reverse leakage protection, and high line/load regulation make this device ideal for use in space-constrained, battery-powered designs.

Working Principle

The MAX1589ETT250+T is a low-dropout linear voltage regulator. The device works by allowing a control voltage to be internally generated for a given input voltage. This control voltage is compared to an internal reference voltage to generate an error signal that is combined with an external compensation network to form a loop. This error signal is then used to adjust the output voltage by controlling the amount of current that is passing through the internal series pass transistor. This current is then regulated by adjusting the gate voltage of the series pass transistor, thus maintaining the output voltage at the desired level.

Features

The MAX1589ETT250+T offers a slew of features that make it an ideal fit for a variety of designs. These features include a low voltage dropout of 200mV at 250mA, a typical dropout voltage of 0.3V at 1A load current, 1% initial accuracy, and temperature coefficient of 0.03%. Additionally, protection against reverse biases on the output and extremely low quiescent current of 95uA, make it well suited for battery powered applications. The device is also immunity to shock, vibration and electromagnetic interference, allowing for excellent noise filtering.

Conclusion

The MAX1589ETT250+T is a high-performance, thermally efficient linear voltage regulator designed by Texas Instruments. Its wide input range, low dropout voltage, low temperature drift, and excellent line/load regulation make it ideal for low power regulated supplies in space-constrained applications. This makes it an ideal fit for a variety of systems, including automotive, industrial and general-purpose, as well as battery-powered designs.
