NEGATIVE LOW DROPOUT REGULATOR

General Description

The 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.
