The UCC283TDTR-3G3 is a high-performance low-dropout linear regulator (LDO) manufactured by Texas Instruments, designed to deliver a continuous 3A of output current with a dropout voltage of typically 340mV at full load. This device is part of a family of LDOs that offer a range of output voltages, making them suitable for a variety of applications.

Key Features

• Output Voltage: The UCC283TDTR-3G3 provides a fixed output voltage of 3.3V, which is ideal for powering 3.3V logic and ICs in a circuit.
• High Output Current: With an ability to supply up to 3A of output current, this LDO can support high-current applications such as powering FPGAs, microprocessors, and DSPs.
• Low Dropout Voltage: The typical dropout voltage of 340mV ensures efficient operation, even when the supply voltage is close to the output voltage, which is crucial for battery-powered devices.
• Thermal and Overcurrent Protection: The device includes built-in thermal shutdown and overcurrent protection features to safeguard the regulator and the load from damage due to overheating or excessive current draw.
• Adjustable Output: An external resistor divider can be used to adjust the output voltage, providing flexibility for different application requirements.
• Stable with Low ESR Output Capacitors: The LDO is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than other capacitor types, allowing for a more compact and cost-effective design.
