Electrical Characteristics
LM4132-2.5 (V
OUT = 2.5V)
Limits in standard type are for T
J = 25˚C only, and limits in boldface type apply
over the junction temperature (T
J) range of -40˚C to +125˚C. Minimum and Maximum limits are guaranteed through test, de-
sign, or statistical correlation. Typical values represent the most likely parametric norm at T
J = 25˚C, and are provided for ref-
erence purposes only. Unless otherwise specified V
IN = 5V and ILOAD =0
