The 2 µs turn-off is fast enough to isolate a faulted rail before the supply droops. If your design requires a specific power-up sequence between multiple rails, this asymmetric delay matters: the load gets power slowly but drops quickly on a fault or disable. ## Package and footprint — SC-70-6 The SC-70-6 (SOT-363) body is 2.0 mm × 1.25 mm, with 0.65 mm pin pitch. A 2-layer board with minimal copper pours will hit the thermal ceiling faster than a 4-layer with a solid ground plane.","metaTitle":"TI LM66100DCKR P-Channel Power Switch, 1.5 A, 1.5 V–5.5 V","metaDescription":"Texas Instruments LM66100DCKR P-Channel load switch, 1.5 A max, 1.5 V to 5.5 V supply, 27 µs turn-on, 2 µs turn-off, SC-70-6, -40°C to 105°C.
