NOTES:

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

12. Dropout is defined by the difference in supply VIN and VOUT when the supply produces a 2% drop in VOUT from its nominal value.

Electrical Specifications Unless otherwise noted, 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 “ISL78310 Schematic

Block Diagram” on page 4 and Tech Brief TB379. Boldface limits apply over the operating temperature range, -40°C to +125°C. (Continued)
