The LM2671N-12/NOPB is a step-down (buck) switching regulator capable of delivering a fixed output voltage of 12V at a maximum load current of 500mA. It operates with a wide input voltage range from 8V to 40V and features high efficiency, achieving up to 96% under optimal conditions. The device includes a 260 kHz fixed frequency internal oscillator, which allows for smaller filter components compared to lower frequency regulators. This regulator is designed with a ±1.5% maximum output voltage tolerance over specified line and load conditions, ensuring reliable performance. It incorporates essential protection features such as thermal shutdown and current limiting, enhancing its robustness in various applications. The LM2671N-12/NOPB is available in an 8-pin PDIP package, making it suitable for straightforward integration into designs with minimal external components required.
