The TAEJIN LM2951D-5.0 is a fixed 5.0V low-dropout linear regulator designed to deliver up to 100mA of current. Featuring a dropout voltage of 450mV at full load and a quiescent current of 120µA, it provides efficient and stable power conversion from higher voltage rails. The 8-SOP package offers a robust, through-hole or surface-mount option for a wide range of industrial, automotive, and consumer applications requiring a reliable 5V supply.
- Standard 5V Output: Directly powers 5V logic and microcontrollers without additional conversion stages.
- Wide Input Flexibility: Can step down from common 9V, 12V, or 24V rails, making it versatile for multi-voltage systems.
- Low Quiescent Current: The 120µA Iq helps minimize power consumption in battery-backed or always-on applications.
- Reliable 8-SOP Package: Industry-standard package with good thermal performance for 100mA loads.
