TYPICAL PERFORMANCE CHARACTERISTICS (continued)
V_IN = +5.0V, C1 = C2 = C3 = 3.3µF for SP6830, C1 = C2 = C3 = 1µF for SP6831, and T_AMB = 25^OC unless otherwise
noted. The SP6830/6831 devices use the circuit found in when obtaining the following typical performance
characteristics (unless otherwise noted).
