The MCP1755T-3302E/MC is a linear voltage regulator belonging to the PMIC (Power Management Integrated Circuits), Voltage Regulators and Linear product categories. It occupies an important space in industrial, commercial and consumer electronics designs that require stable, low drop-out voltage regulation. This voltage regulator employs a band gap reference as its output reference voltage, to guarantee zero output voltage drift over time. Due to its small size, low output noise and line/load regulation features, it is suitable for a wide range of applications from factory automation and machine-to-machine communication to consumer electronics. This document provides a brief overview of the features and working principles of the MCP1755T-3302E/MC.

The MCP1755T-3302E/MC comes in a tiny 3-lead SC70 package and is a low drop-out (LDO) linear voltage regulator able to regulate both positive and negative voltages. It has an output voltage range of 1.0V to 12.0V with a maximum output current of 150mA. The main features include extended input-output differential up to 2V, very low quiescent current of 88uA and low drop-out voltage of 200mV. Its thermal shutdown and overload protection features combined with its low power consumption makes it ideal for modern, power-sensitive designs.

The MCP1755T-3302E/MC has impressive line regulation of 0.2mV/V and load regulation of 0.85mV/mA. The output voltage is regulated by a proprietary band gap reference which ensures zero output voltage drift over time. The external resistor network adjusts the feedback voltage to the desired voltage output. It also has a low power-on reset circuitry which ensures an accurate and reliable system reset. In addition, its internal architecture is optimized for fast transient response.

The MCP1755T-3302E/MC is suitable for a wide range of applications. These applications include, but are not limited to, general power supplies, batteries and charger circuits, USB adapters and portable electronics, automotive electronics and smart metering. This voltage range has adequate performance to supply power to efficient low power systems, such as ARM Cortex-M processors and low power sensor nodes. It can also replace a single winding transformer in AC-DC converters, making it an ideal choice for high density switching power supplies.

In conclusion, the MCP1755T-3302E/MC is a low drop-out, linear voltage regulator from the PMIC, Voltage Regulators and Linear product categories. It is suitable for a wide range of applications, from factory automation to consumer electronics and smart metering. Its low output noise, line/load regulation and high output voltage range make it a versatile, power-sensitive choice product designers can trust.
