The Texas Instruments LM2990SX-5.0 is a three-terminal, low-dropout, 1-A negative voltage regulator. It is designed to provide a stable -5V output voltage, making it suitable for various power management applications.
Key electrical specifications include an input voltage range of -26V to -6V and an output current capability in excess of 1A. The dropout voltage is typically 0.6V at a 1A load, with a worst-case maximum of 1V across the operating temperature range. The quiescent current is low, typically 1mA with a 1A load and an input-output voltage differential greater than 3V.
This regulator offers 5% output accuracy over its entire operating range. It also features internal short-circuit current limiting and internal thermal shutdown with hysteresis for enhanced reliability. The device is rated for operation over the junction temperature range of -40°C to 125°C.
The LM2990SX-5.0 is available in a TO-263 package, suitable for through-hole mounting. It is a functional complement to the LM2940 series.
The input voltage range is -26 V to -6 V.
It provides a fixed output voltage of -5 V, with an accuracy of 5% over the entire operating range.
The regulator can deliver output current in excess of 1 A.
Typical dropout voltage is 0.6 V at a 1-A load, with a worst-case maximum of 1 V over the entire operating temperature range.
Quiescent current is typically 1 mA with a 1-A load current and input-output differential greater than 3 V, and typically 9 mA in dropout mode.
The operating temperature range is -40°C to 125°C.
The LM2990SX-5.0 is available in a 3-pin TO-263 (KTT) surface-mount package, supplied in tape and reel.
