Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 4: The KILL turn-on blanking time is the waiting period immediately  
after the enable output is asserted. This blanking time allows sufficient  
time for the regulator and the µP to perform power-up tasks. The KILL, PB,  
and ON inputs are ignored during this period.  
Note 2: All currents into pins are positive; all voltages are referenced to  
GND unless otherwise noted.  
Note 3: Guaranteed by design, not subject to test.  
Note 5: The enable lockout time is the waiting period immediately after the  
enable output is released. It allows an application to properly power-down  
such that the next power-up sequence starts from a consistent powered  
down configuration. PB and ON are ignored during this period.
