SNVS165A – JUNE 2001 – REVISED MAY 2013

Electrical Characteristics

VCC = full range, TA = −40°C to +105°C, unless otherwise noted. Typical values are at TA = +25°C, VCC = 5V for

4.63/4.38/4.00 versions, VCC = 3.3V for 3.08/2.93 versions, and VCC = 3V for 2.63 version.

At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT23-3 package must be

derated at 4mW/°C at ambient temperatures above 70°C. The device has internal thermal protection.
