Electrical Characteristics
LM4132-2.5 (V
OUT
= 2.5V)
over the junction temperature (T
) range of -40C to +125C. Minimum and Maximum limits are guaranteed through test, de-
sign, or statistical correlation. Typical values represent the most likely parametric norm at T
J
= 25C, and are provided for ref-
erence purposes only. Unless otherwise specified V
IN
= 5V and I

= 0
Limits in standard type are for T
J
= 25C only, and limits in boldface type apply
