4 / 21 page LM10011 SNVS822 – DECEMBER 2012 www.ti.com ELECTRICAL CHARACTERISTICS Limits in standard type are for TJ = 25°C only. Limits appearing in boldface type apply over the full operating junction temperature range (–40°C < TJ < +125°C). Unless otherwise noted, specifications apply to the Typical Application Circuit.
