The National Semiconductor LM2957HVM-5.0/NOPB is a high-voltage, fixed 5.0V low-dropout (LDO) linear regulator specifically designed for automotive and industrial applications where robust performance and transient protection are critical. It delivers a stable 5.0V OUTPUT ONLY voltage rating with a maximum OUTPUT ONLY current rating of 250mA. Housed in a thermally efficient TO-252 package, this surface-mount device (SMD) provides excellent heat dissipation. The LM2957HVM-5.0/NOPB operates reliably across a broad operating temperature range of –40°C to 125°C, making it suitable for harsh environments. Its high input voltage tolerance and reverse battery protection simplify circuit design and enhance system reliability. Common use cases include automotive ECUs, industrial control systems, and battery-powered devices requiring a regulated 5V supply. The absence of lead (NOPB) makes it compliant with RoHS standards.
