STMicroelectronics L4979MD013TR Linear Regulator: Precision Power Management for Demanding Applications
The STMicroelectronics L4979MD013TR linear voltage regulator combines high performance with robust protection features, making it an ideal solution for precision power management in industrial, automotive, and consumer electronics. This 5V fixed-output regulator delivers up to 150mA of current with an ultra-low dropout voltage of just 0.4V, ensuring efficient operation across a wide range of input voltages (up to 31V). Its advanced design balances compactness with reliability, featuring integrated thermal shutdown and short-circuit protection to safeguard connected systems.
Key Performance Characteristics
Engineered for modern electronics, this 20-SOIC packaged regulator excels in applications requiring stable voltage regulation under varying load conditions. With a quiescent current of only 20µA and maximum supply current of 3mA, it minimizes power consumption while maintaining 55dB PSRR (100Hz) for noise-sensitive circuits. The device's wide operating temperature range (-40°C to 150°C) ensures reliable performance in extreme environments, from industrial control systems to automotive electronics.
