The TC1264-3.3VDB is a linear voltage regulator designed for small, portable USB and low power applications. It is capable of delivering up to 3.3V or 4A of regulated power from a single power source. The regulator comes with a few key features which include low quiescent current, high frequency regulation, low output noise, fast yet precise current and voltage regulation, and automatic thermal protection.

The device features two different operating modes: linear and pulse frequency mode. In linear mode, the input voltage is applied directly to the regulator and the output voltage is regulated by the on-chip voltage reference. The reference voltage is adjustable through two external resistors and the output voltage can be adjusted up to 3.3V. When the device is in pulse frequency mode, the output voltage is regulated by an on-chip oscillator which delivers a rapid yet precise current and voltage regulation.

The TC1264-3.3VDB is also highly efficient and operates at wide temperature ranges. It is protected against reverse, over-voltage, and over-temperature conditions. The on-chip thermal protection circuit can be used to ensure the thermal regulation of the device, preventing any damage or fault from excessive heat and current.

The TC1264-3.3VDB is ideal for powering small portable USB devices, such as portable music players, digital cameras, and wireless communication systems. It can also be used in low power residential and commercial applications, such as LED lighting and security systems. Its low quiescent current, high frequency regulation, low output noise, and rapid yet precise current and voltage regulation make it an excellent choice for these applications.

In summary, the TC1264-3.3VDB linear voltage regulator is a highly efficient device with a host of features that make it ideal for powering small, portable USB and low power applications. It features two operating modes and it has built-in protection against reverse, over-voltage and over-temperature conditions. Its low quiescent current, high frequency regulation, low output noise, and rapid yet precise current and voltage regulation make it an excellent choice for powering small, portable USB devices, as well as for low power residential and commercial applications.
