LM2991QML
The LM2991 is a low dropout adjustable negative regulator with a output voltage range between −2V to −25V. The LM2991 provides up to 1A 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 1A load current is typically 0.6V and a guaranteed worst-case maximum
of 1V over the entire operating temperature range. The quiescent current is typically 1 mA with a 1A load current and an input-output
voltage differential greater than 3V. A unique circuit design of the internal bias supply limits the quiescent current to
only 9 mA (typical) when the regulator is in the dropout mode (VO − VI
The LM2991 is short-circuit proof, and thermal shutdown includes hysteresis to enhance the reliability of the device when inadvertently overloaded for extended periods.
