2) 500mA Continuous current load
3) Active”High”Control Logic
4) Soft start function
5) Over current detection（Output Off-latch Operating）
6) Thermal shutdown
7) Open drain error flag output
8) Under voltage lockout
9) Power supply voltage range 2.7V~5.5V
10) Operating temperature range-40°C~85°C
11) SSOP5 Package
