Application Hints  
EXTERNAL CAPACITORS  
Output Capacitor ESR Range  
The LM2991 regulator requires an output capacitor to main-  
tain stability. The capacitor must be at least 10 µF aluminum  
electrolytic or 1 µF solid tantalum. The output capacitor’s  
ESR must be less than 10, or the zero added to the regu-  
lator frequency response by the ESR could reduce the  
phase margin, creating oscillations. The shaded area in the  
Output Capacitor ESR graph indicates the recommended  
ESR range. An input capacitor, of at least 1 µF solid tantalum  
or 10 µF aluminum electrolytic, is also needed if the regulator  
is situated more than 6 inches from the input power supply  
filter.  
DS011260-5  
MINIMUM LOAD  
A minimum load current of 500 µA is required for proper op-  
eration. The external resistor divider can provide the mini-  
mum load, with the resistor from the adjust pin to ground set  
to 2.4 k.  
SETTING THE OUTPUT VOLTAGE  
The output voltage of the LM2991 is set externally by a resis-  
tor divider using the following equation:  
=
VOUT VREF x (1 + R2/R1) − (IADJ x R2)  
=
where VREF  
−1.21V. The output voltage can be pro-  
grammed within the range of −3V to −24V, typically an even
