The LM2990S-5.0/NOPB from Texas Instruments is a three-terminal, negative low-dropout voltage regulator. It is designed to provide a stable -5V output voltage with an output current capability in excess of 1A. The device features a wide input voltage range from -26V to -6V.
Key electrical specifications include a typical dropout voltage of 0.6V at a 1A load, with a maximum of 1V across the operating temperature range. The quiescent current is typically 1mA under a 1A load. For protection, the regulator incorporates internal short-circuit current limiting and thermal shutdown with hysteresis.
This regulator is suitable for applications requiring a negative voltage rail, such as post-switcher regulation or local on-card regulation in battery-operated equipment. Its functional complement to the LM2940 series makes it a useful component in dual-supply systems.
The LM2990S-5.0/NOPB is available in a TO-263-4, D²Pak surface mount package. It is designed for operation over a temperature range of -40°C to 125°C.
The input voltage range is -26V to -6V.
The output voltage is -5V.
The output current is in excess of 1A.
The dropout voltage is 1V at 1A.
It has Over Temperature and Short Circuit protection.
The operating temperature range is -40°C to 125°C.
It is supplied in a TO-263-4, D²Pak (3 Leads + Tab), TO-263AA package and is a Surface Mount type.
