SP6828 Datasheet, PDF (6/17 Pages) Sipex Corporation – +3V Low Power Voltage Inverters

TYPICAL PERFORMANCE CHARACTERISTICS
V_IN = +3.3V, C1 = C2 = C3 = 10µF for SP6828, C1 = C2 = C3 = 3.3µF for SP6829, and T_AMB = 25^oC unless
otherwise noted. The SP6828/6829 devices use the circuit found in Figure 19 when obtaining the following typical
performance characteristics (unless otherwise noted).
