MCP1824ST-3002E/DB

PMIC stands for power management integrated circuit. Voltage regulators are known as an integral part of PMIC offering. They are used to provide a constant regulated electrical power from a source of ever-changing input voltage. LINEAR voltage regulators are used to regulate the voltage using linear method. MCP1824ST-3002E/DB is an adjustable linear voltage regulator.

Application Field

The MCP1824ST-3002E/DB is an adjustable linear voltage regulator aimed to provide a cost-effective replacement for conventional transformer-based linear regulators. This device is especially designed for portable applications powered by single-cell Li-Ion and Li-Polymer cells needing a regulated output of fixed voltage from as low as 0.5V to as high as 3.6V. This device offers an adjustable mode of operation and can be used as a single Li-Ion/Li-Polymer battery charger circuit. It can also be used for any application that needs an adjustable voltage range.

Working Principle

The MCP1824ST-3002E/DB operates in a linear mode. It uses a linear voltage regulator, HV etch, p-channel MOSFET and an internal load switch to provide the required regulated output voltage. The MCP1824ST-3002E/DB has a very low line/load regulation of 0.2%. Such Line/Load regulations helps to provide reliable and precise regulated voltage. The device also features over voltage protection and current limit protection.

In the adjustable mode the MCP1824ST-3002E/DB uses internal voltage reference and an external resistor divider to set the desired output voltage. The output voltage can be adjusted from 0.5V to 3.6V. This device uses Digital Programmable Enable to reduce the quiescent current in battery powered applications. This enables the device to operate for longer duration.

The device also offers thermal shutdown protection, current limit and inrush current limiting protection.The inrush current limit protection reduces the inrush current surge and helps to reduce the noise generated by the power supply.

Conclusion

The MCP1824ST-3002E/DB is an adjustable linear voltage regulator designed for providing reliable and precise regulated output voltage. It is an ideal choice for applications powered by single-cell Li-Ion and Li-Polymer cells. With programs such as over voltage protection, current limit protection, thermal shutdown protection, and inrush current limit protection, the MCP1824ST-3002E/DB is a great fit for any application that requires an adjustable voltage range.
