Texas Instruments LM2990S-5-0 is a negative fixed voltage linear regulator with a -5V output and a maximum output current of 1.8A. This device is housed in a TO-263 (DDPAK-3) surface-mount package, suitable for demanding applications. It offers a voltage input range up to -26V and features robust protection against over-temperature and short circuits. With a quiescent current of 1mA and a maximum supply current of 5mA, it maintains efficiency in operation. The regulator provides a Power Supply Rejection Ratio (PSRR) of 58dB at 1kHz, contributing to cleaner power delivery. The LM2990S-5-0 is commonly utilized in automotive, industrial, and consumer electronics where reliable negative voltage regulation is critical.
