Fixed LDO Voltage Regulator 3.3V Out 1.5A TO-263-3

The Texas Instruments Fixed LDO Voltage Regulator is a low dropout positive regulator designed to provide a reliable and stable 3.3V output. Delivering up to 1.5A of load current, this regulator features a typical dropout voltage of just 1.3V, making it highly efficient for various power management applications. It shares the same pin-out as the industry standard LM317, ensuring easy integration into existing circuit board designs.

This fixed output voltage version integrates the necessary adjust resistors, simplifying your circuit layout and reducing external component count. The internal circuitry incorporates advanced features such as a Zener trimmed band gap reference, current limiting, and thermal shutdown protection. These protective measures ensure the safety and longevity of both the regulator and the connected components under demanding operating conditions.

Key Performance Features

• Precision Regulation: Offers 0.015% typical line regulation and 0.1% typical load regulation for a consistent and stable output.
• Stable Operation: Designed to operate effectively with non-ceramic output capacitors.
• Robust Protection: Built-in current limiting and thermal shutdown capabilities safeguard against overcurrent and overheating.

With an input voltage range spanning from 2.6V to 27V and an operating temperature range of -40°C to 125°C, this surface-mount device in a TO-263-3 package is exceptionally versatile. It is an ideal choice for power management solutions requiring a dependable and precise 3.3V supply.
