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 45 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 3.5 A|
|Swtiching Frequency at 0-A load||Not critical: Need >1.85 MHz at high load only|
|Current Consumption at 0-A load||Critical: Need to ensure low current consumption to reduce battery drain|
