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. 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. Applications must follow thermal guidelines of the package to determine worst case junction temperature. Please refer to Applications section of the datasheet and Tech Brief TB379. Boldface limits apply over the operating temperature range, -40°C to +125°C. (Continued) PARAMETER SYMBOL TEST CONDITIONS MIN (Note 11) TYP MAX (Note 11) UNITS ISL80101 |
