PRODUCTION DATA.
TI highly recommends a CIN greater than CL, because of the integrated body diode in the NMOS switch. A CL greater than CIN can cause the voltage on VOUT to exceed VIN when the system supply is removed. This could result in current flow through the body diode from VOUT to VIN. TI recommends a CIN to CL ratio of 10 to 1 for minimizing VIN dip caused by inrush currents during startup.
