The MAX666EPA+ voltage regulators from Maxim Integrated are low-power, high-precision CMOS linear regulators used commonly in electronic devices and mobile devices. The MAX666EPA+ is a 5V, low-noise, fixed voltage-regulator IC with a maximum input voltage of 6V, with guaranteed load and line regulation and output noise. It is a miniature version of the MAX666ESA/.ESA+ devices and is only available in the 8-pin TDFN and 8-pin SOIC packages.

The MAX666EPA+ is based on CMOS technology and uses fewer external components than traditional bipolar designs, thus improving system efficiency and reducing power consumption. This device offers an adjustable voltage output, selectable dropout voltage, and no external components required, making it an ideal choice for use in a wide range of applications, such as high-performance computing, mobile phones, navigation systems, and portable audio. Its features, such as low voltage start-up and high power supply rejection ratio (PSRR), along with its low noise profile, make it highly suitable for battery-operated devices.

At the heart of the MAX666EPA+ voltage regulator is a voltage reference sensing line that incorporates a bandgap reference and current-limiting circuitry. This circuitry senses the input voltage, regulates the output voltage, and provides an automatic built-in temperature coefficient and coefficient tracking. The temperature coefficient ensures that the output voltage stays regulated over temperature, preventing device failures due to excessive heat. The coefficient tracking technology ensures the stable output voltage against output load change and input voltage variations.

The MAX666EPA+ voltage regulator is capable of delivering up to 200mA of continuous current with a maximum dropout voltage of 0.4V. It also features an inhibit line, over-temperature protection, and an enable/shutdown control pin. The enable/shutdown control pin enables or shuts down the device automatically, depending on current drawn. This puts the device into low-power state, saving precious energy.

The MAX666EPA+ voltage regulator is available in fixed output voltage grades and is designed to operate over a wide temperature range. Its small size, low quiescent current, low noise, and low dropout voltage make it ideal for battery-powered applications as well as space-constrained applications. The MAX666EPA+ is also suited for gaming devices, automotive applications, and portable sensing devices, among others.

The MAX666EPA+ voltage regulator is a highly useful device for electronic systems in need of a high-precision, low-power linear regulator. Its small size and low operating power requisite make it suitable for tightly confined applications. In addition, its low dropout voltage, low quiescent current, high PSRR, and enhanced temperature coefficient ensure that the output voltage remains in a safe range, even when subjected to extreme environmental conditions or rapid load changes.
