... Current Limit and Thermal Protection T9167 includes a current limit which monitors and controls the pass transistor's gate voltage limiting the output current to 350mA Typ. (700mA Typ. for RT9167A). Thermal- overload protection limits total power dissipation in the RT9167/A. When the junction temperature exceeds T = 155° ...
