NTE1924
Integrated Circuit
Positive 3 Terminal Voltage Regulator,
24V, 1.5A
Description:
The NTE1924 is a monolithic voltage regulator integrated circuit in a TO3 type package designed for
use in applications requiring a well regulated positive output voltage. Outstanding features include
full power usage up to 1.5A of load current, internal current limiting, thermal shutdown, and safe area
protection on the chip, providing protection of the series pass Darlington, under most operating condi-
tions. A low noise, temperature stable band gap reference is the key design factor insuring excellent
temperature regulation. This, coupled to a very low output impedance, insures superior performance
and load regulation.
