LM7812CT/NOPB Linear Voltage Regulator IC Positive Fixed 1 Output 1A TO-220-3
The LM7812CT/NOPB is a high-performance linear voltage regulator from Texas Instruments (TI), designed to deliver a stable 12V DC output with a maximum load current of 1A. Housed in a compact TO-220-3 package, this three-terminal regulator simplifies power supply design by integrating thermal shutdown, internal current limiting, and output transistor safe-area compensation. It operates with an input voltage range of 14.5V to 35V, making it suitable for industrial, automotive, and consumer electronics applications requiring reliable 12V power distribution. Its low dropout voltage (2V at 1A) and ±2% output voltage tolerance ensure consistent performance across varying loads and temperatures (0°C to 125°C).
LM7812CT/NOPB Voltage Regulator IC Key Features & Benefits
The LM7812CT/NOPB combines robust protection mechanisms with ease of use. Key features include overcurrent protection, short-circuit immunity, and thermal overload shutdown, safeguarding both the IC and downstream components. Its fixed 12V output eliminates the need for external feedback resistors, reducing board space and BOM costs. The regulator's low quiescent current (8mA) enhances efficiency in light-load conditions, while its compatibility with ceramic output capacitors improves transient response. Additionally, its TO-220 package supports heat sinking for extended thermal management, enabling reliable operation in high-power or high-temperature environments.
