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

Note 1. Load and line regulation are specified at constant junction temperature. Changes in VO
due to heating effects must be taken into account spearately. Pulse testing with low duty
cycle is used.
