* The pin numbering scheme for the micro SMD package was revised in April 2002 to conform to JEDEC standard. Only the pin numbers were
revised. No changes to the physical location of the inputs/outputs were made. For reference purposes, the obsolete numbering scheme had VEN
as pin 1, GND as pin 2, VOUT as pin 3, VIN as pin 4, and BYPASS as pin 5.
