Product Overview

The LM2991S/NOPB is a negative low dropout Adjustable Regulator with a output voltage range between -3 to -24V. The LM2991 provides up to 1A of load current and features a On/Off pin for remote shutdown capability. The regulator uses new circuit design techniques to provide a low dropout voltage, low quiescent current and low temperature coefficient precision reference. 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 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 9mA (typical) when the regulator is in the dropout mode (VOUT - VIN ≤ 3V).
  • Low quiescent current
  • Internal short-circuit current limit
  • Internal thermal shutdown with hysteresis
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
