NEGATIVE LOW DROPOUT REGULATOR
General DescriptionThe LM2990 is low dropout, 1 ampere negative voltage regulator available with fixed output
voltages of -5, -12, and -15V.
The LM2990 uses new circuit design techniques to provide low dropout and low quiescent
current. 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 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 (typical) when the regulator is in the dropout mode (Vout - Vin < 3V).
Output voltage accuracy is guaranteed to +5% over load, and temperature extremes.
The LM2990 is short-circuit proof, and thermal shutdown includes hysteresis to enhance the
reliability of the device when overloaded for an extended period of time.
