PRODUCTION DATA.
To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns on into a discharged load capacitor, a capacitor needs to be placed between VIN and GND. A 1-µF ceramic capacitor, CIN, placed close to the pins, is usually sufficient. Higher values of CIN can be used to further reduce the voltage drop in high-current application. When switching heavy loads, it is recommended to have an input capacitor about 10 times higher than the output capacitor to avoid excessive voltage drop.
