Quality Control: Learn More
The Texas Instruments LP5951MG-1-8 is a fixed 1.8V positive linear voltage regulator designed for high-performance applications. It delivers a stable output current of 150mA with a low quiescent current of 55 µA and a supply current of 70 µA (max). This device features excellent power supply rejection ratio (PSRR) of 60dB to 50dB across the 100Hz to 10kHz frequency range, making it suitable for noise-sensitive circuits.
The LP5951MG-1-8 boasts a low dropout voltage of 0.35V at 150mA, enabling efficient operation even with minimal voltage headroom. Protection features include over current, over temperature, and short circuit protection. The regulator is housed in a compact SC-70-5 surface mount package and operates over an extended temperature range of -40°C to 125°C. Applications include portable electronics, automotive, and industrial systems requiring reliable voltage regulation.
