NOTES:

9. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

10. Dropout is defined by the difference in supply VIN and VOUT when the output is below its nominal regulation.

Electrical Specifications Unless otherwise noted, all parameters are established over the following specified conditions:

VIN =VOUT + 0.4V, VOUT = 5.0V, CIN = COUT = 10µF, TJ = +25°C, ILOAD = 0A. Applications must follow thermal guidelines of the package to

determine worst case junction temperature. Please refer to “Functional Description” on page 7 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 TJ = TA defines

established limits. (Continued)
