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.

NOTES:
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
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. Electromigration specification defined as lifetime average junction temperature of +110°C where max rated DC current =
lifetime average current.
11. Minimum cap of 10µF X5R/X7R on VIN and VOUT required for stability.
12. 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.
