• 2.7 V to 5.5 V input
• Adjustable current-limit up to 3 A
• Reverse current flow blocking
• 90 µA typical on-state supply current
• 1 µA typical off-state supply current
• 50 mO maximum on-resistance
• Open-drain fault flag
• Thermal shutdown
• Thermal-shutdown output latch (MIC2549A)
• 2 ms (slow) soft-start turn-on, fast turnoff
• Available with active-high or active-low enable

Applications:

• USB power distribution
• PCI Bus Power Switching
• Notebook PC
