5 / 31 page LMZ12001EXT www.ti.com SNVS661G – JUNE 2010 – REVISED SEPTEMBER 2015 Electrical Characteristics (continued) Limits 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. Unless otherwise stated the following conditions apply: VIN = 12 V, VOUT = 1.8 V (1).
