ISL75052SEH Datasheet, PDF (6/16 Pages) Intersil Corporation – 1.5A, Rad Hard, Positive, High Voltage LDO

ISL75052SEH
Electrical Specifications Unless otherwise noted, all parameters are guaranteed over the following specified conditions:
V_IN = V_OUT + 0.5V, V_OUT = 4.0V, C_IN = C_OUT = 2x100µF 60mΩ, KEMET type T541X107N025AH or equivalent, T_J = +25°C, I_L = 0A. Applications must follow
thermal guidelines of the package to determine worst case junction temperature. Please refer to “Applications Information” on page 7 of the data sheet
and Tech Brief TB379. Boldface limits apply over the operating temperature range, -55°C to +125°C. Pulse load techniques used by ATE to ensure T_J = T_A
defines guaranteed limits. (Continued)
