The REG113NA-3.3/3K from Texas Instruments is a high-performance, fixed-output linear voltage regulator designed to deliver a stable 3.3V output with a maximum current of 400mA. This surface-mount device (SOT23-5 package) is optimized for low-dropout operation, featuring a dropout voltage of just 0.41V at 400mA, making it ideal for power-sensitive applications. With an input voltage range up to 10V and a quiescent current of 500 µA, it balances efficiency and performance. The regulator includes enable control and robust protection features such as over-current and over-temperature shutdown, ensuring reliability in demanding environments.
This regulator is ideal for:
The REG113NA-3.3/3K stands out for its low dropout, high PSRR, and integrated protections, making it a superior choice for applications demanding precision and reliability. Its small form factor, enable control, and low quiescent current further enhance its versatility across portable, industrial, and embedded systems. While marked as Last Time Buy, its ROHS3 compliance and REACH unaffected status ensure it remains a viable solution for legacy and new designs alike.
