NCV47700DAJR2G Description

The NCV47700DAJR2G from onsemi is a high-performance, adjustable positive linear voltage regulator designed for automotive-grade applications. With an input voltage range up to 40V and an adjustable output voltage from 5V to 20V, it delivers a stable 350mA output current while maintaining low dropout voltage (0.5V @ 150mA). This regulator integrates advanced protection features, including over-current, over-temperature, and reverse polarity protection, ensuring robust operation in harsh environments. Its low quiescent current (230 µA) and high PSRR (70dB @ 100Hz) make it ideal for noise-sensitive applications. Packaged in an 8-pin SOIC with Tape & Reel (TR), it is optimized for surface-mount assembly.
