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 VIN and VOUT when the supply produces a 2% drop in VOUT from its nominal value. 10. Minimum cap of 10µF X5R/X7R on VIN and VOUT 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 VOUT for application. Electrical Specifications Unless otherwise noted, all parameters are established over the following specified conditions: VIN =VOUT + 0.4V, VOUT = 1.8V, 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 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 TJ = TA defines established limits.
