NTE971
Linear Integrated Circuit
Voltage Regulator, Negative, –24V, 1A
Description:
The NTE924 fixed–voltage regulator is a monolithic integrated circuit in a TO220 type package de-
signed for use in a wide variety of applications including local, on–card regulation. This regulator em-
ploys internal current limiting, thermal shutdown, and safe–area compensation. With adequate heat
sinking it can deliver output currents in excess of 1A. Although designed primarily as a fixed regulator,
this device can be used with external components to obtain adjustable voltages and currents.
Features:
D No External Components Required
D Internal Thermal Overload Protection
D Internal Short–Circuit Current Limiting
D Output Transistor Safe–Area Compensation
