Typical Performance Characteristics (continued)
Unless otherwise specified, the following conditions apply: V_IN = 12V; C_IN = three x 10μF + 47nF X7R Ceramic; C_OUT = two x
330μF Specialty Polymer + 47 uF Ceramic + 47nF Ceramic; C_FF = 4.7nF; Tambient = 25° C for waveforms. All indicated
temperatures are ambient.
Thermal derating V_IN = 12V, V_OUT = 3.3V
