LM2990T-12V/1A Negative Low Dropout Regulator Price in Pakistan

The LM2990 is a three-terminal, low dropout, 1-ampere negative voltage regulator available with a fixed output voltage of −12v. 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 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 (VOUT − VIN ≤ 3V). Output voltage accuracy is guaranteed to ±5{7e82c6d62784066d1b113f595afb6e15f0ca3fec289cddd29e600df910d44428} overload and temperature extremes.
