Quality Control: Learn More
STMicroelectronics L4989D is a positive fixed output linear voltage regulator IC. This component provides a stable 5V output with a maximum current capability of 150mA. Designed for surface mount applications, it is housed in an 8-SOIC package. Key features include an enable pin, a reset output, and a watchdog timer for robust control. The device offers protection against over-temperature and short circuits. With a quiescent current of 69 µA and a maximum input voltage of 31V, the L4989D exhibits a low dropout voltage of 0.4V at 150mA. Its Power Supply Rejection Ratio (PSRR) is 55dB at 100Hz. This regulator is suitable for automotive and industrial applications.
