MCP1701A-3302I/TO

MCP1701A-3302I/TO is one of the most popular Voltage Regulators which falls within the Linear category of Power Management ICs (PMIC). This Voltage Regulator is perfectly suited for applications where stability, ripple rejection and low quiescent current are needed. These devices are also known for their low sag and transient response.

Application Field

MCP1701A-3302I/TO Voltage Regulator is designed to provide an adjustable output voltage that can range from 1.25V to 5.5V. This makes it ideal for applications such as remote control pulses with low power consumption, low frequency/low ripple power supply, 3.3V logic supply, servo and brushed DC motor control, and switching power supply. This Voltage Regulator is widely used in battery-operated systems, such as Cellular phones, Bluetooth headsets, Cordlessphones, Digital cameras and Remote controls.

Working Principle

MCP1701A-3302I/TO Voltage Regulator uses a linear regulation topology to achieve an accurate, stable output voltage. When the regulation voltage is set, the Voltage Regulator constantly measures the output voltage. The regulation voltage is compared to the output voltage, and if the output voltage is lower than the regulation voltage, more current is sent through the resistor connected between the output and the feedback pin. Conversely, if the output voltage is higher than the regulation voltage, less current is sent through the resistor. This process is repeated at a frequency determined by the time constant of the external resistor; this frequency is the loop compensation frequency. As a result, the output voltage remains stable. In addition, the MCP1701A-3302I/TO Voltage Regulator is designed with quiescent current shutdown and thermal shutdown protection features, making it suitable for a wide range of applications.

Conclusion

With its low quiescent current, low sag and ripple rejection capabilities, MCP1701A-3302I/TO Voltage Regulator is perfect for applications where stability, minimal ripple and low quiescent current are desired. Its adjustable output voltage range of 1.25V to 5.5V is suitable for a wide range of low-power applications. Lastly, its thermal and quiescent current protection features make it safe for short-term failure conditions. Thus, the MCP1701A-3302I/TO Voltage Regulator is a great option for applications where these features are required.
