Integrated Circuit
Negative 3 Terminal Voltage Regulator,
–15V, 1.5A
Description:
The NTE1919 is a 3 terminal fixed negative voltage regulator 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 conditions.
Hermetically sealed steel packages are utilized for high reliability and low thermal resistance. A low–
noise temperature stable band–gap reference is the key design factor insuring excellent temperature
regulation of the NTE1919. This coupled to a very low output impedance insures superior load regula-
tion.

Note 1. Short circuit protection is only assured to VINmax. In case of short circuit, with input–output
voltages approaching VINmax, regulator may require the removal of the input voltage to restart.
