5 / 28 page LM3503 www.ti.com SNVS329E – JULY 2005 – REVISED MAY 2013 Electrical Characteristics (1)(2) (continued) Limits in standard typeface are for TJ = +25°C. Limits in bold typeface apply over the full operating junction temperature range ( −40°C ≤ TJ ≤ +125°C). Unless otherwise specified,VIN = 2.5V.
