SNVS099I – MAY 1999 – REVISED OCTOBER 2016 LM2991 Negative Low-Dropout Adjustable Regulator
1 Features 1 3 Description
The LM2991 is a low dropout adjustable negative
regulator with a output voltage range between -3 V to
-24 V. The LM2991 provides up to 1 A of load
current and features a ON /OFF pin for remote
shutdown capability. Output Voltage Adjustable from -3 V to -24 V,
Typically -2 V to -25 V
Output Current in Excess of 1 A
Dropout Voltage Typically 0.6 V at 1-A Load
Low Quiescent Current
Internal Short Circuit Current Limit
Internal Thermal Shutdown With Hysteresis
TTL, CMOS Compatible ON/OFF Switch
Functional Complement to the LM2941 Series The LM2991 uses new circuit design techniques to
provide a low dropout voltage, low quiescent current
and low temperature coefficient precision reference. …
