The LM2990T-15/NOPB is a three-terminal low-dropout negative Voltage Regulator for use with local on-card regulation and battery operated equipment. The LM2990 uses circuit design techniques to provide low-dropout 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. The 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 ensured to ±5% over load and temperature extremes. The LM2990 also implements short-circuit proof and thermal shutdown includes hysteresis to enhance the reliability of the device when overloaded for an extended period of time.
● Low quiescent current
● Internal short-circuit current limit
● Internal thermal shutdown with hysteresis
● 5% Output accuracy over entire operating range
● Output current in excess of 1A
● Dropout voltage typically 0.6V at 1A load
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
