(1) Maximum output current is affected by the PCB layout, metal trace width, number of layers, ambient temperatrue and other environmental factors. Thermal limitations of the system must be carefully considered.
(2) Startup time = time from EN assertion to 0.95 × VOUT(NOM).
(3) RPULLDOWN specification only applies to devices with active output discharge. These devices have a P in the part number, indicating the device has active output discharge.
