MCP1825ST-3302E/DB Voltage Regulators Application and Working Principle

The MCP1825ST-3302E/DB Voltage Regulators are manufactured by Microchip Technology Inc. The device is part of the PMIC (Power Management ICs) series and is categorized as Linear Voltage Regulators. The MCP1825ST-3302E/DB is designed for use in circuits where a lower output voltage needs to be produced from a higher input voltage. It is ideal for processors, FPGAs, ASICs, general-purpose regulators, and certain analog circuits.

General Features

The MCP1825ST-3302E/DB is designed to efficiently convert an unregulated voltage source into a regulated output voltage waveform. The device features a maximum operating temperature range of –40°C to +125°C, 7mA output current, low dropout voltage (200mVtyp @7mA), 3.2 V to 28 V input voltage range, -2.5% voltage regulation accuracy, output voltage range of 1.2 V to 11.5 V, and quiescent current of 20 µAmax. The device is well-suited for low-power, low-noise, low-cost power management applications and is available in a SOT-23 package.

Functional Description

The MCP1825ST-3302E/DB is a linear voltage regulator with an input voltage range of 3.2 V to 28 V and an adjustable output voltage range of 1.2 V to 11.5 V. It features an integrated feedback loop to regulate the output voltage and is capable of operating at output currents up to 7mA. The device provides excellent line and load regulation. Under no-load conditions, the quiescent current is low, resulting in extended battery life.

Norminal Operation

The MCP1825ST-3302E/DB operates in two modes, depending on the output voltage. When the output voltage is greater than 4V, the device runs in a constant voltage mode. In this mode, the error amplifier maintains a constant output voltage, independent of changes in the load current. When the output voltage is less than 4V, the device operates in a constant current mode. In this mode, the output current is kept constant, independent of changes in the load voltage.

Application Field

The MCP1825ST-3302E/DB is well-suited for low-power, low-cost power management applications. The device’s features make it ideal for voltage regulation in processors, FPGAs, ASICs, and analog circuits. Additionally, it can be used as a replacement for linear regulators in compatible low-power projects where noise and cost considerations are important.

Conclusion

The MCP1825ST-3302E/DB is a linear voltage regulator with an adjustable output voltage range of 1.2 V to 11.5 V at up to 7mA. It is ideal for low-power, low-noise, low-cost power management applications, such as processors, FPGAs, ASICs, general-purpose regulators and certain analog circuits, as well as as a replacement for linear regulators in compatible projects.
