LM2991 - Negative Low Dropout Adjustable Regulator

This page provides the datasheet information for the LM2991, a member of the LM2 Negative Low Dropout Adjustable Regulator family.

Datasheet Summary

Description

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

24V.

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.
