UA78Mxxyyyz
xx is the nominal output voltage (for example, 05 = 5.0V, 15 = 15.0V).
yyy is the package designator.
z is the package quantity.

Devices can ship with the legacy chip (CSO: SFB) or the new chip (CSO: RFB). The reel packaging label provides CSO information to distinguish which chip is being used. Device performance for new and legacy chips is denoted throughout the data sheet.
