Typical Application
3 Description
The LM2990 is a three-terminal, low-dropout, 1-A negative voltage regulator available with fixed output voltages of
- 5 V,
- 5.2 V,
- 12 V, and
- 15 V.
The LM2990 uses circuit design techniques to provide low-dropout and low-quiescent current. The dropout voltage at 1-A load current is typically 0.6 V and an ensured worst-case maximum of 1 V over the entire operating temperature range. The quiescent current is typically 1 m A with 1-A load current and an input-output...
