Where:
• V_S = Supply voltage = 5V
• I_SMAX = Maximum quiescent supply current = 375mA
• V_OUT = Maximum output voltage of the application = 2V
• R_LOAD = Load resistance tied to ground = 150
• n = 1 to 15 channels

airflows. At the thermal resistance equation shows, the
required thermal resistance depends on the maximum
ambient temperature.
