LM2991QML  
Negative Low Dropout Adjustable Regulator  
General Description  
Features  
The LM2991 is a low dropout adjustable negative regulator  
with a output voltage range between −2V to −25V. The  
LM2991 provides up to 1A of load current and features a  
On /Off pin for remote shutdown capability.  
Output voltage adjustable from −2V to −25V  
Output current in excess of 1A  
Dropout voltage typically 0.6V at 1A load  
Low quiescent current  
The LM2991 uses new circuit design techniques to provide a  
low dropout voltage, low quiescent current and low tempera-  
ture 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 internal bias supply limits the qui-  
escent current to only 9 mA (typical) when the regulator is in  
the dropout mode (VO − VI 3V).  
Internal short circuit current limit  
Internal thermal shutdown with hysteresis  
TTL, CMOS compatible ON/OFF switch  
Functional complement to the LM2941 series  
Applications  
Post switcher regulator  
Local, on-card, regulation  
The LM2991 is short-circuit proof, and thermal shutdown in-  
cludes hysteresis to enhance the reliability of the device when  
inadvertently overloaded for extended periods.
