LD29300V33 Description

Short technical summary and product information.

The STMicroelectronics LD29300V33 is a high-current, low-dropout voltage regulator designed for demanding applications. It provides a fixed 3.3V output with a guaranteed current capability of up to 3A. A key feature is its very low dropout voltage, typically 0.4V at 3A, which is crucial for maximizing battery life and efficiency in power-sensitive systems.

 

This regulator includes internal current and thermal limit protection, enhancing system reliability. The TO-220 package with through-hole mounting makes it suitable for various power supply designs, including post-regulation for switching power supplies, monitors, VCRs, TVs, computer systems, and battery-powered devices. Its high PSRR ensures clean power delivery even in noisy environments.

 

Designed for robust performance, the LD29300V33 operates within a temperature range of -40°C to 125°C. Its fixed output voltage is guaranteed with ±1% tolerance at 25°C, ensuring precise voltage regulation for connected components. The device is also available in other fixed voltage versions and an adjustable version, catering to a wide range of design requirements.
