The SP619 is a low RDS(ON) high current switch designed with precision current lim-
iting to protect connected devices from damage due to a short circuit condition or
against current surges that may cause the supply voltages to fall out of regula-
tion. This switch is functional over an input voltage range of 2.5V to 7V, but is targeted
at 5V applications. The SP619 is also protected from thermal overload which
limits power dissipation. In shutdown mode, the supply current drops to 2?/SPAN>A.
