LM10504 Datasheet, PDF (9/35 Pages) Texas Instruments – Triple Buck + LDO Power Management Unit

16.0 LDO Electrical Characteristics (Note 3, Note 4) Unless otherwise noted, V_IN = 5.0V where: V_IN =
V_{IN_B1} = V_{IN_B2} = V_{IN_B3}. Limits appearing in normal type apply for T_J = 25°C. Limits appearing in boldface type apply over the
entire operating junction temperature range of −30°C ≤ T_A = T_J ≤ +85°C.
