TYPICAL PERFORMANCE CHARACTERISTICS
VIN = +5.0V, C1 = C2 = C3 = 10µF for SP828, C1 = C2 = C3 = 3.3µF for SP829, and TAMB = 25oC unless
otherwise noted. The SP828/829 devices use the circuit found in Figure 19 when obtaining the following typical
performance characteristics (unless otherwise noted).
