Note 1: ABSOLUTE MAXIMUM RATINGS ARE THOSE VALUES BEYOND WHICH THE LIFE
OF A DEVICE MAY BE IMPAIRED.
Note 2: THE LT3464E IS GUARANTEED TO MEET PERFORMANCE SPECIFICATIONS
FROM 0 ° C TO 70 ° C. SPECIFICATIONS OVER THE – 40 ° C TO 85 ° C OPERATING
TEMPERATURE RANGE ARE ASSURED BY DESIGN, CHARACTERIZATION AND CORRELATION
WITH STATISTICAL PROCESS CONTROLS.
Note 3: CURRENT CONSUMED BY DISCONNECT PNP WHEN THERE IS NO LOAD ON
