F ceramic bypass capacitor between IN and GND, close to the device is recommended. The
output capacitor should be chosen based on the size of the load during the transition of the switch. A 47-
μ
F
capacitor is recommended for 10-mA loads. Typical output capacitors (xx
μ
F, shown in Figure 24) required for
a given load can be determined from Figure 16 which shows the output voltage droop when output is switched
from IN2 to IN1. The output voltage droop is insignificant when output is switched from IN1 to IN2. Additionally,
bypassing the output with a 0.01-
μ
F to 0.1-
μ
F ceramic capacitor improves the immunity of the device to
short-circuit transients.
