Electrical Characteristics
Unless otherwise stated the following conditions apply: V
IN = 48V, VCC = 10V, RT = 26.7 k, RSET = 20 k. (Note 4). Limits in
standard type are for T
J = 25°C only; limits in boldface type apply over the Operating Junction Temperature (TJ) range of -40°C
to +125°C
. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent
the most likely parametric norm at T
J = 25°C, and are provided for reference purposes only.
