PRODUCT(1) DESCRIPTION
LP2982vwxxy-z.z/NOPB

v is the accuracy specification for the legacy chip (A or blank). See the Section 5.5 for more information. This character is insignificant for the new chip.w is the operating temperature range (I = −40°C to +125°C).xx is the package designator (M5 = SOT-23).y is the reel designator size. See the Package Addendum for more information on package quantity.z.z is the nominal output voltage (for example, 3.3 = 3.3 V; 5.0 = 5.0 V)./NOPB indicates material construction that does not use Lead (Pb). This device ships with either the legacy chip (CSO: DLN or GF8) or the new chip (CSO:RFB), which uses the latest manufacturing flow. 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 document.
