The MCP1727-ADJE/MF is a high-preformance and ultra-low-power linear voltage regulator which belongs to the family of PMIC, a type of Voltage Regulators. The MCP1727 is integrated with a 2-A load switch, a reverse-battery protection, a brown-out reset, over-voltage protection, and a voltage supervisor. It is built with a wide input voltage range of 4.5 to 28 V and provides fast output transition time. Suitable for low-voltage, low-power system designs, the MCP1727-ADJE/MF is a high-performance voltage regulator ideal for space-constrained applications and industrial battery-supplied systems.

The MCP1727-ADJE/MF integrates two front-end MOSFETs to regulate voltage in complement to the low drop-out (LDO) internal power pass element. It also gives a precise output voltage that is programmable from 0.75 to 5.25 V, with an accuracy better than ±5% over the operating junction temperature range of -40 to 125°C. The external MOSFET makes it more flexible to efficiently regulate a wide input voltage supplier, from 4.5 to 28 V. This also makes it easily adaptable to automotive and industrial supplies as well as battery-powered applications like personal electronic devices. The internal reset/pressure regulator handles up to four external interrupting loads such as LEDs without the need of an external driver. It also features a maximum power rating of 45 W.

It is cost-effective compared to other voltage regulators due to its wide input-voltage range and power rating. The temperature-sensing diode and integrated MOSFETs provide high-output avalanche and over-voltage protection. Its ability to operate with a ripple current up to 100 mA makes it a good choice for cost-sensitive applications, and its small size of 5 0.5mm x 3 0.5mm facilitates its use in small, space-constrained applications. Its built-in external adjustment mode and synchronization capabilities permit asynchronous transitions and ensure that all related regulation tasks are managed in a single integrated IC.

The MCP1727-ADJE/MF is designed for applications that require maximum precision and flexibility. Coupled with its low quiescent current of 0.45 μA in idle mode, it can meet the most demanding low-power requirements. Its ultra-low shutdown current of 0.1 μA ensures very low power consumption and maximizes the power efficiency of applications. The integrated load switch and over-voltage protection guarantee a safe system operation in applications.

The MCP1727-ADJE/MF is an ideal linear voltage regulator, suitable for low-voltage, low-power system designs. It has a wide input voltage range of 4.5 to 28 V and provides fast output transition time. It offers superior output accuracy and high-output Avalanche and over-voltage protection, as well as an external adjustment mode and synchronization capabilities. Finally, its low quiescent current and ultra-low shutdown current ensure low power consumption and maximum power efficiency.
