†C1 = 1 μF solid tantalum or 10 μF aluminum electrolytic required for stabilit
*C2 = 1 μF solid tantalum is required only if regulator is more than 4″ from power-supply filter capacitor
Output capacitors in the range of 1μF to 1000 μF of aluminum or tantalum electrolytic are commonly used to provide improved output impedance and rejection of transients
