LM2990T-5.0 P+

The LM2990 is a three-terminal, low-dropout, 1-A
negative voltage regulator available with fixed output
? Fixed Output Voltages: ?5 V, ?5.2 V, ?12 V, and voltages of ?5 V, ?5.2 V, ?12 V, and ?15 V.
?15 V
The LM2990 uses circuit design techniques to ? 5% Output Accuracy over Entire Operating Range provide low-dropout and low-quiescent current. The
? Output Current in Excess of 1 A dropout voltage at 1-A load current is typically 0.6 V
? Dropout Voltage Typically 0.6 V at 1-A Load and an ensured worst-case maximum of 1 V over the
entire operating temperature range. The quiescent ? Low Quiescent Current
current is typically 1 mA with 1-A load current and an
? Internal Short-Circuit Current Limit input-output voltage differential greater than 3 V. A
? Internal Thermal Shutdown with Hysteresis unique circuit design of the internal bias supply limits
? Functional Complement to the LM2940 Series the quiescent current to only 9 mA (typical) when the
regulator is in the dropout mode (VOUT ? VIN ? 3 V).
