The SP619 is a low RDS(ON) high current switch designed with precision current limiting 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 regulation. 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 2µA.

- Available in small SOT23-6 package
- Drop-in replacement to National Semiconductor's LM619
