6 / 36 page LMZ10505 SNVS633I – JANUARY 2010 – REVISED SEPTEMBER 2015 www.ti.com Electrical Characteristics (continued) Specifications are for TJ = 25°C unless otherwise specified. Minimum and maximum limits are ensured through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. VIN = VEN = 3.3 V, unless otherwise indicated in the conditions column.
