3 Description
The LM2991 is a low dropout adjustable negative regulator with a output voltage range between
- 3 V to
- 24 V. The LM2991 provides up to 1 A of load current and features a ON /OFF pin for remote shutdown capability.
The LM2991 uses new circuit design techniques to provide a low dropout voltage, low quiescent current and low temperature coefficient precision reference. 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...
