NTE957
Integrated Circuit
3–Terminal Adjustable Negative
Voltage Regulator
Description:
The NTE957 is an adjustable 3–terminal negative voltage regulator in a TO220 type package capable
of supplying in excess of –1.5A over a –1.2V to –37V output range. The circuit design has been optimized
for excellent regulation and low thermal transients. Further, the NTE957 features internal current limiting,
thermal shutdown, and safe–area compensation, making this device virtually blowout–proof against
overloads.
The NTE957 serves a wide variety of applications including local on–card regulation, programmable–
output voltage regulation or precision current regulation. The NTE957 is the ideal complement to the
NTE956 adjustable positive regulator.
Features:
D Output Voltage Adjustable from –1.2V to –37V
D Guaranteed 1.5A Output Current
D Line Regulation Typically 0.01%/V
D Load Regulation Typically 0.3%

Note 1. Although power dissipation is internally limited, these specifications are applicable for power
dissipations of 20W.
Note 2. Regulation is measured at constant junction temperature, using pulse testing with a low duty
cycle. Changes in output voltage due to heating effects are covered under the specification
for thermal regulation.
