The MAX1976AETA150+T is a voltage regulator in the PMIC (Power Management Integrated Circuit) family, classified under the Voltage Regulators – Linear umbrella. Built with CMOS technology, the regulator provides an ideal solution for battery powered systems due to its small size, low standby current and outstanding PSRR. It is also capable of providing low voltage and high current output to applications hosted in space-constrained devices.

The MAX1976AETA150+T voltage regulator is a low dropout linear regulator that is targeted towards devices that require low voltage output and high current capabilities. It operates on an input supply of 2.2V to 5.5V and provides an output voltage of 0.9V to 4.6V with better than 1% accuracy. In addition, the voltage regulator is available in SOT23-5 package, making it easy to incorporate into small form factor designs with tight space constraints.

The MAX1976AETA150+T regulator is designed to provide a low voltage and high current output. This is achieved through a minimum input and output voltage differential of 200mV which allows for very low current draw from the input to the output. The regulator also offers a high output current rating of 150mA and an intelligent dropout voltage that helps maintain stability and output accuracy. A low standby current rating of only 4uA helps extend the life of the battery in applications that need to maintain long periods of inactivity.

The MAX1976AETA150+T voltage regulator works by using a series of voltage dividers and charge pumps to ensure accuracy. A supply voltage is divided down with several resistors and capacitors, forming the input voltage. This voltage is compared with the output voltage being provided by the regulator, which is adjustable and within the range of 0.9V to 4.6V. In order to match the input and output voltages, the regulator will use a charge pump to make the adjustment. The charge pump will then output a higher or lower voltage depending on the difference between the input and output voltages.

The performance of the MAX1976AETA150+T voltage regulator is complemented by the outstanding power supply rejection ratio (PSRR) of its low dropout architecture. This helps reduce the frequency and magnitude of noise generated by changes to its power supply voltage, which can be a common problem in battery-powered systems. Furthermore, its wide input voltage range is conducive to operation in demanding conditions, making the MAX1976AETA150+T particularly suitable for mobile and aerospace applications.

Overall, the MAX1976AETA150+T voltage regulator is an ideal choice for a wide range of applications including mobile devices, aerospace systems and battery-powered systems. Its wide input voltage range and high output current capability allow it to easily meet the demands of an ever-growing number of applications. Furthermore, its low dropout architecture and high PSRR ensure smooth operation in any application requiring a low voltage and high current output.
