NTE967
Linear Integrated Circuit
Voltage Regulator, Negative, –12V, 1A
Description:
The NTE967 is a negative voltage regulator in a TO220 type package that employs current limiting,
thermal shutdown, and safe–area compensation which makes it remarkably rugged under most oper-
ating conditions. With adequate heat–sinking they can deliver output currents in excess of 1.0 am-
peres.
Features:
D Thermal Short Circuit and safe Area Protection
D High Ripple Rejection

Note 1. For calculations of junction temperature rise due to power dissipation, thermal resistance
junction–to–ambient (R_thJA) is 50°C/W (no heat sink) and 5°C/W (infinite heat sink).
