Negative 3 Terminal Voltage Regulator
–12V, 1.5A
Description:
The NTE1915 is a 3 terminal negative regulator in a TO3 type package with a fixed output voltage
of –12V and up to 1.5A load current capability. Where other voltages are required, the NTE1911 pro-
vides an output voltage range of –1.2V to –37V.
This device needs only one external component – a compensation capacitor at the output, making
it easy to apply. Worst case guarantees on output voltage deviation due to any combination of line,
load, or temperature variation assure satisfactory system operation.
Exceptional effort has been made to make the NTE1915 immune to onerload conditions. This regula-
tor has current limiting which is independent of temperature, combined with thermal overload protec-
tion. Internal current limiting protects against momentary faults while thermal shutdown prevents
junction temperatures from exceeding safe limits during prolonged overloads.
Although primarily intended for fixed output voltage applications, the NTE1915 may be programmed
for higher output voltages with a single resistive divider. The low quiescent drain current of the device
allows this technique to be used woth good regulation.

Note 1. Regulation is measured at constant junction temperature. Changes in output voltage due
to heating effects must be taken into account separately. To ensure constant junction tem-
perature, low duty cycle, pulse testing is used. The NTE1915 does have low thermal feed-
back, improving line and load regulation. On all other tests, even though power dissipation
is internally limited, electrical specifications apply only up to PD.
