The MAX5087BATN+ is a linear, low-dropout (LDO) regulators, produced by Maxim Integrated Solutions, that features an ultra-low 2.3μA supply current, an extended input-voltage range, and a power-good flag. It offers support for loads of up to 200mA, and can operate as a standalone device or configured in an application through an external resistor. Additionally, it is perfect for low-power applications that require efficient power conversion. This article will provide an overview of the MAX5087BATN+ application field and working principle.

Integrated Features

The MAX5087BATN+ features a wide range of integrated features including built-in over-temperature and reverse-voltage protection. Furthermore, it is supplied in a miniature 6-pin SC-70 package and is available with fixed output voltages of 1.8V, 2.5V, 3.3V and 5.0V. The MAX5087BATN+ meets high-efficiency standards, offering an output ripple of <25mV, with extremely light output capacitance and low quiescent current.

Applications

The device is ideal for applications in mobile phones, tablet PCs and handheld devices because it is designed to deliver low-noise power into modern single-"rail" systems. It also caters for computer peripherals, set-top boxes, DSL/Cable modems, disk drives, and other applications. Additionally, its long-term power stability is achieved through its constant-current limit protection and thermal shutdown.

Working Principle

The MAX5087BATN+ works by first sensing the input voltage and controlling the gate voltage applied to the MOSFET-pass device to maintain a constant output voltage. The current-limit protection keeps the output current limited to an amount that is set by an external resistor connected between the current-limit terminal (VCL) and ground. The constant-current drain feature provides external devices with the ability to draw constant-current independent of the input voltage. The device will operate as long as the output current stays within the specified limit.

Conclusion

The MAX5087BATN+ integrated linear LDO regulator offers high-accuracy output voltage, low-noise power, low shutdown current and excellent power-supply rejection for noise-sensitive applications. Its wide range of features make it an ideal choice for various power-conversion applications. The MAX5087BATN+ provides a simple and cost-effective solution for a wide range of low-power applications.
