6 / 30 page LM3102, LM3102-Q1 SNVS515H – SEPTEMBER 2007 – REVISED JUNE 2015 www.ti.com Electrical Characteristics (continued) Specifications with standard type are for TJ = 25°C unless otherwise specified. Minimum and Maximum limits are specified 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. Unless otherwise stated the following conditions apply: VIN = 18 V, VOUT = 3.3 V.
