LM2991 - Negative Low Dropout Adjustable Regulator

Download the LM2991 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same negative low dropout adjustable regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2991 is a low dropout adjustable negative regulator with a output voltage range between 3V to

24V.

Key Features

  • a On /Off pin for remote shutdown capability. The LM2991 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 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 int.

LM2991 Negative Low Dropout Adjustable Regulator May 1999 LM2991 Negative Low Dropout Adjustable Regulator General Description The LM2991 is a low dropout adjustable negative regulator with a output voltage range between −3V to −24V. The LM2991 provides up to 1A of load current and features a On /Off pin for remote shutdown capability. The LM2991 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 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.
