Description
Dual LDO with Low Noise, Low IQ, and High PSRR, the KKZ11 is a high performance electronic component model. It is capable of sourcing 150mA current from Channel 1, and 300mA from Channel 2. The device has a low standby current and high-PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200mΩ. The KKZ11 is designed to integrate two high performance LDOs, providing excellent transient response to large current steps and load regulation of 1% voltage change across the full range of load current. With a wide input voltage capability of 2.3V to 6.5V, the KKZ11 is suitable for a variety of electronic applications. Its tiny 10 Ld 3x3mm DFN package makes it easy to incorporate into any design.
