PMIC - Voltage Regulators - Linear

The IFX25001TFV33ATMA1 is a linear voltage regulator designed to provide precise step-down voltage regulation in an integrated format. It is designed to be used in high-voltage applications, providing a 5V regulated output in a wide input voltage range of 3V to 60V with accurate regulation. The device has an internal start-up circuit with internal voltage reference and a low dropout voltage. It includes a diagnostic output to report a fault condition in the system.

Application Field

The IFX25001TFV33ATMA1 is ideal for a wide range of applications requiring precise voltage regulation, including industrial systems, communications, automotive, computer/computer peripherals and instrumentation. It is suitable for use in applications where power supply noise must be reduced, as it provides a very low-noise voltage output.

Working Principle

The IFX25001TFV33ATMA1 employs linear regulation to provide a precise output voltage. It adjusts the output voltage by comparing the internal reference voltage to the feedback voltage at the FB pin. When the two voltages differ, an error signal is provided to the error amplifier, which adjusts the duty cycle of the power transistor to reduce the output voltage.

The device has an internal start-up circuit including a low dropout voltage, and is capable of driving up to 5A of current at its output. It also has an overload protection circuit that prevents operation in the overload condition and an overload reset circuit that shuts down the output voltage in case of fault.

Conclusion

The IFX25001TFV33ATMA1 is a linear voltage regulator that provides precise step-down voltage regulation in an integrated format. It is ideal for a wide range of applications requiring precise voltage regulation, particularly in systems where power supply noise must be reduced. With its low dropout voltage, overload protection circuit, and overload reset circuit, it is a reliable device for providing accurate and stable voltage control.
