Electrical Specifications Unless otherwise noted, all parameters are established over the following specified conditions:
V IN = V OUT + 0.4V, V OUT = 1.8V, C IN = C OUT = 10 μ F, T J = +25 ° C, I LOAD = 0A. Applications must follow thermal guidelines of the package to
determine worst case junction temperature. Please refer to “Functional Description” on page 12 and Tech Brief TB379 .
Boldface limits apply over the operating temperature range, -40°C to +125°C. Pulse load techniques used by ATE to ensure T J = T A defines
established limits. (Continued)

NOTES:
8. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
9. Dropout is defined by the difference in supply V IN and V OUT when the supply produces a 2% drop in V OUT from its nominal value.
10. Minimum cap of 10μF X5R/X7R on V IN and V OUT required for stability.
11. If the current limit for in-rush current is acceptable in application, do not use this feature. Used only when large bulk capacitance required on V OUT for
application.
