LM2990T-12 Datasheet PDF - TI

●The LM2990T-12 is a -12V fixed output negative low-dropout (LDO) Linear Regulator. The device uses circuit design techniques to provide low-dropout (LDO) and low-quiescent current. The dropout voltage at 1A load current is typically 0.6V and an ensured worst-case maximum of 1V over the entire operating temperature range. The quiescent current is typically 1mA with 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 9mA when the regulator is in the dropout mode (VOUT - VIN <=3 V). Output voltage accuracy is ensured to ±5% over load and temperature extremes.
