Example requirements for a typical 3.3-V application. The input voltages are here for illustration purposes only. See Electrical Characteristics for minimum operating input voltage. The minimum input voltage necessary to achieve proper output regulation depends on the components used. See Figure 42 for typical drop-out behavior.
|DESIGN PARAMETER||EXAMPLE VALUE|
|Input voltage range||8-V to 18-V steady-state, 4.0-V to 36-V transients|
|Output current||0 A to 5.5 A|
|Switching Frequency at 0-A load||Not critical: Need >330 kHz at high load only|
|Current Consumption at 0-A load||Critical: Need to ensure low current consumption to reduce battery drain|
