PRODUCT VOUT
LP2982cxxxzX-y.y/NOPB

Legacy chip

 c is the accuracy specification.xxx is the package designator.z is the package quantity.
X is for a large-quantity reel and non-X is for a small-quantity reel.
y.y is the nominal output voltage (for example, 3.3 = 3.3 V; 5.0 = 5.0 V).

LP2982AxxxzX-y.y/M3

New chip

 A is for higher accuracy and non-A is for standard grade.
xxx is the package designator.z is the package quantity.
X is for a large-quantity reel and non-X is for a small-quantity reel
y.y is the nominal output voltage (for example, 3.3 = 3.3 V; 5.0 = 5.0 V).
M3 is a suffix designator for newer chip redesigns, fabricated on the latest TI process technology.
