RESET Output for LM809, RESET output for LM810.

6.5 Electrical Characteristics

VCC = full range, TA = –40°C to 105°C, unless otherwise noted. Typical values are at TA = 25°C, VCC = 5 V for 4.63, 4.38, and

4.00 versions, VCC = 3.3 V for 3.08 and 2.93 versions, and VCC = 3 V for 2.63 and 2.45 version

(1).
