Frequently Asked Questions
What is the output voltage and maximum output current of the UCC283TDKTTT-3?
The UCC283TDKTTT-3 provides a fixed 3.3V output with a maximum continuous output current of 3A. The typical dropout voltage is 0.5V, and the maximum dropout voltage is 1V at full load, making it suitable for high-current 3.3V power rails.
What is the input voltage range for the UCC283TDKTTT-3?
The UCC283TDKTTT-3 accepts an input voltage ranging from a minimum of 3.45V to a maximum of 9V absolute. This wide input range makes it compatible with 5V and 7.5V upstream supplies commonly found in industrial and telecom applications.
What package does the UCC283TDKTTT-3 come in, and what are its thermal benefits?
The UCC283TDKTTT-3 is available in a TO-DPAK (D2PAK) surface-mount package, which offers a large exposed pad for efficient heat dissipation. This package is ideal for high-current linear regulator applications where thermal management is critical to maintaining reliable 3A output.
What are typical applications for the UCC283TDKTTT-3 LDO regulator?
Typical applications include point-of-load regulation for FPGAs, microcontrollers, DSPs, and logic circuits requiring a stable 3.3V supply. It is also used in industrial automation, telecommunications equipment, and embedded systems where a low-noise, high-current 3.3V rail is essential.
Is the UCC283TDKTTT-3 adjustable or fixed output?
The UCC283TDKTTT-3 is a fixed-output LDO regulator set at 3.3V. It does not support output voltage adjustment. For applications requiring a different output voltage, Texas Instruments offers adjustable LDO variants in the UCC283 family.
