a
Setting Output Voltage (VOUT) or alphanumeric custom code.
b
Setting Output Voltage
1: standard (a: output voltage; DC/DC output voltage
= LDO output voltage
2: custom code (a: custom code; DC/DC output voltage
≠ LDO output voltage
c
Designation of chip enable and Mode pin polarities
A: CE; "H" active, Mode pin; "H"
=DC/DC converter mode, "L"=LDO Mode
B: CE; “H” active, Mode pin; “L”
=DC/DC converter mode, “H”=LDO Mode
d
Designation of Taping Type; (Refer to Taping Specification)"TR" is prescribed as a standard.
