ISL75051SRH Datasheet, PDF (7/15 Pages) Intersil Corporation – 3A, Rad Hard, Positive, Ultra Low Dropout Regulator

ISL75051SRH
Electrical Specifications Unless otherwise noted, all parameters are guaranteed over the following specified conditions:
V_IN = V_OUT + 0.4V, V_OUT = 1.8V, C_IN = C_OUT = 220µF 25mΩ and 0.1µF X7R, 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 11 of the datasheet 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)

NOTES:
8. Parameters with MIN and/or MAX limits are 100% tested at -55°C, +25°C and +125°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
9. Line and Load Regulation done under pulsed condition for T<10ms.
10. Dropout is defined as the difference between the supply V_IN and V_OUT, when the supply produces a 2% drop in V_OUT from its nominal value. Data
measured within a 3ms period.
