The LM2794 has an active-low shutdown pin (LOW = shutdown, HIGH = operating). The
LM2795 has an active-high shutdown pin (HIGH = shutdown, LOW = operating) that has a
pull-up to V
IN.

C2+
Positive terminal of C2
A3
P
OUT
Charge pump output
(*) Note that 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 purpose, the obsolete numbering had C1+ as pin 1, C1- as pin 2, VIN as pin
3, GND as pin 4, C2- as pin 5, D1-D4 as pin 6,7,8 & 9, Iset as pin 10, BRGT as pin 11, SD as pin 12, C2+ as pin 13, Pout as pin 14
