Typical Applications
LM2931 Fixed Output
525404
*Required if regulator is located far from power supply filter.
**C2 must be at least 100 μF to maintain stability. May be increased without bound to maintain regulation during transients. Locate as close as possible to the
regulator. This capacitor must be rated over the same operating temperature range as the regulator. The equivalent series resistance (ESR) of this capacitor is
critical; see curve.
LM2931 Adjustable Output
525405
due to the input bias current of the ADJ pin (approximately 1 μA).
Note: Using 27k for R1 will automatically compensate for errors in V
